United just posted a secret sale to Buenos Aires, Argentina last night that has lasted well into today, slurpee day (7/11), from several corners from the country.

From departure points such as Los Angeles, Washington DC (Dulles), and New York City you can get to Buenos Aires LATER THIS MONTH for only about 600$ total. For high tourist season in the United States, that's a downright steal. So if you haven't got plans for the kids' summer vacation, now is the time to strike.

Check your local airport to see if there are similar deals or cheap connections to a target city.

And don't forget -- it's winter down in Argentina right now, so you might want to consider a trip over to the Andes for some skiing or maybe some time down in Patagonia watching some glaciers fight. You also might want to pick up a couple kilos of some of that delicious Mendozan wine and that Argentine steak while you're down there.

If you're worried about visas, American's don't need any pre-departure paperwork for immigration.

To book the ticket, use a flex search on Kayak over the next few weeks to find availability. You shouldn't have a problem finding seats for flights later this month.

Happy Trails!

Got some free time over the next three weeks? Delta just launched a promo offering 9,999 miles for each rental with one of their auto partners Avis or Budget. Each qualifying rental gets you the miles, regardless of how long you keep the vehicle, as long as you book with Delta's Car Search tool. You have until the end of the month to rent and you need to sign up to become a SkyMiles member first.

Sure, you may not be traveling three times in the next month, but do you need to? If you can get three car rentals cheap enough, the time and money invested in getting a car at the airport for 24 hours can easily be less than a domestic ticket that you could book with miles.

Rental car fees vary wildly across geographical boundaries, but almost every airport in the country has either an Avis or a Budget rental car location. And many of those rural locations have plenty of inventory (at damn good prices) available for the rest of July.

Here in Detroit, a car rental over a weekend night on Budget is about 55$. Times three is 165$ for 29,997 miles or an award ticket. In Kalamazoo, a more rural airport near where my parents live, it's 24$. That's 72$ for a flight.

Sure, you have to factor in what you're going to DO with the car and what you're going to do with YOUR car while you have the rental. You could always just take it home or to a parking lot and park it. Or park it on the lawn of the rental company.

But it's not a bad way to rack up a few frequent flyer miles to use for future adventure on Delta Airlines.

What could you do with 25k miles or a domestic award ticket? You could fly from your freezing hometown in New Hampshire down to Phoenix next January to get some sun and play some golf while your coworkers freeze. You could fly to Colorado to get some kick ass skiing in next May. You could pay for your girlfriend to come visit you next time you're in San Diego on business.

Sound like a good use for your 74$ invested this month?

You just don't see that many cheap tickets to Tegucigalpa, the capital of Honduras that often, so when this gem came along I just had to spread the word.

The Panamanian airline Copa is offering some pretty sweet fares around 300$ total between New York's JFK airport and Tegucigalpa (TGU) that are good for late this summer and into fall, perhaps because Toncontín airport is kind of a hazard and they're trying to drum up business once shoulder season comes up.

You may have read recently (perhaps in light of Kent's Plane Answers article) that TGU is closing down temporarily to rectify some of their runway and approach issues -- bear in mind that Copa may reroute you to San Pedro instead. No worries, that's just down the street.

And as far as Tegucigalpa goes as a destination? I haven't heard a lot of great things about the capital, proper, but the city is 60 miles away from the Pacific Ocean and within spitting distance of El Salvador and Nicaragua. At the very least you use these cheap tickets as a stepping stone to your real vacation in Central America.

Tickets appear to be valid across a wide variety of dates starting in September but excluding Thanksgiving weekend. Use a flex search on Kayak to find dates that work for you.

For those who solo travel, bargains are harder to come by, particularly if you're booking a cruise or taking a tour. Most tour prices are couple friendly. If you have a traveling buddy, lodging is cheaper.

Ed Perkins, a consumer travel writer for Tribune Media Services offers some suggestions for people who are going it alone to reduce the cost of an adventure.

One option is to have a cruise line or cruise operator find a roommate for you. Perhaps someone is in the same position you are. You would only be sharing a room, but the rest of the time you can strike out on your own.

Another is to look for a traveling companion by hitting up your friends, coworkers, family members, basically anyone you know, to find out if they know of someone who would like to go on a trip.

Check out an organization like Connecting Solo Travel Network, Travel Acquaintance and Travel Chums. These businesses specialize in hooking people up to single travel deals and with each other.

Perkins also suggests O Solo Mio Tours and scouting out last minute deals with tour operators. Sometimes you can get a good deal right before a trip starts.

Even for people traveling with a partner, hooking up with a single person can be a money saver and can offer a broader experience. When my husband and I were traveling in Vietnam we became friends with Amit, a woman from Israel. We shared a room and hired a driver together, and even arranged to meet up with her in Hanoi after we veered in different directions for a few days.

We also hung out with Stan, a Vietnam vet who was traveling alone. After sharing a meal, we shared the cost of a driver from Ho Chi Minh City to Nha Trang. Since Stan was stationed in Nha Trang, this gave us an experience from his point of view.

Amit became our companion from Nha Trang to Hue and on to Hoi An.

In Hoi An, Amit and I had a wonderful time shopping while my husband was relieved to not tag along.

I was JUST thinking about this on the ride in this morning when I passed the Shell station at the corner of Platt and Ellsworth when I saw regular fuel at $4.25 a gallon: "Man, I wish I could buy gas at today's price tomorrow".

That's basically what oil futures are: speculators decide that they think the price of oil is going to rise, invest in futures and watch their money go through the roof. More people make money, more speculate and the price goes up. It's the phenomenon that many economists think is leading the surge in oil prices today, beating out real market supply and demand economics and essentially crushing our transportation infrastructure.

The theory is identical to what Southwest Airlines did. Back when oil was at believable prices, that airline decided to hedge their oil purchases and lock in prices at the past rate of $51/barrel. Now that fuel is at over $140, they're making a killing over other airlines.

Now, with gasoline at $4.25 a gallon, you can purchase as many gallons as you want at that price with MyGallons.com and watch the market fluctuate independent of your fuel consumption. If gas keeps surging to $5.00 a gallon? You've just saved a bunch of money. If it drops to $2.50 again? You're out.

Based on how many gallons you buy, the service sends you a "debit" card that lets you purchase as much fuel (per gallon, not dollar) as you have stored up.

The crux of your investment is on where you think the price of the oil is going to head. If you, like many others, think that the price will keep going up, now might be a good time to buy your MyGallons card before your summer road trip.

Subscription to the MyGallons service ranges from $30-$40 per year, but if gas keeps going up that will be a drop in the bucket compared to what you could save.

My mom just arrived back in Columbus this morning at 7 a.m. from her trip to New York City on a Greyhound bus. The bus was one minute early. Wow! I thought that she'd be late due to the wicked thunderstorm that tore through here all last night.

When I pulled into a non-parking space in front of the station (there was just enough room to maneuver behind another car actually parked at a meter), there she was with her small pull behind that she was allowed to carry-on. If she had checked it there would have been no charge.

One more point for Greyhound.

As I posted previously, my mom took the Greyhound because it was cheaper and easier than flying at the time she found out she needed to get to New York. That still seems to be the case.

Unless, you are the woman my mother told me about who got on in Newark, New Jersey.

"Where are you going?" My mother asked her.

"Los Angeles," the woman said.

"My!" said my mother. "When will you get there?"

"Tomorrow."

"Tomorrow?!" My mom wondered how that could be.

That couldn't be. When they changed buses in Pittsburgh, the woman found out she didn't have a clue. She won't arrive in Los Angeles until Saturday.

My mom said she had an accent, so perhaps when someone explained the trip details, she missed something. Obviously.

I hope she didn't have much planned for the next couple of days and thought to bring a good book with her--or several. If nothing else, she snagged the best travel mistake story I've heard in awhile.

(In case you're wondering. If you go from New York to Los Angeles, it will take 2 days, 12 hours and 25 minutes minimum and you would have had to make one bus change. Some schedules take longer with two transfers.You will have traveled 3072 miles. It costs $192 if you don't want a refundable ticket or $215 if you do. There is one ticket left for today's bus that leaves at 11 a.m.)

Perusing your favorite airline's frequent flyer web pages, you may have noticed that many of them offer a service to sell and transfer miles among friends. Points.com is a website that specializes in this task, and many programs from Jetblue to Delta to American Airlines participate in their miles purchasing programs.

Take heed before you get your wallet out and buy miles though: it's a horrible horrible deal. Take a look a these prices for buying miles taken from the Northwest Airlines website:

2,500 = $95
25,000 = $725
30,000 = $865

Now, if you recall from your frequent flyer mile handbook, a domestic ticket costs 25,000 miles -- so this basically equates to buying a ticket for $725. Any ticket, domestically in the US, whether this is between New York and San Francisco or New York and Detroit even if you're having the worst day of your life, shouldn't cost $725. And if it does, you can pretty well be sure that the flight isn't going to have award availability either.

Similarly transferring miles is also expensive:

5,000 = $75
25,000 = $300

With a $25 transaction fee. And the airline isn't even selling miles -- it's just moving them from column A to B in their spreadsheet.

Why would anyone take up this deal? Well, the least irresponsible excuse for buying or transferring miles is because you need to top up your account. You're just short of that 25k or 50k award and need another 5k miles to book your ticket as soon as possible. But it's important to remember the amount of cash you're dumping into your miles just to make them work. If you're dumping $100 dollars into a ticket to get it over 25k and your miles are valued at $0.02/mile (a common market ratio), you've just lost $600 in equity on a ticket. Was the market value of the itinerary that much? Could you have bought the ticket for $200 cash?

If you do find yourself in the above situation, try the following solution: take a deep breath, take your wallet out, hide it under the couch and take a good sharp look at your travel plans and finances for the next six months. There may be a time that you're traveling in the near future during which you can accrue a few more miles and balance out that account.

Or you're short on time and out of money, consider checking Gadlings guide to topping off your frequent flyer account.

After 17 long years of flying America's skies, you've done it. You've almost saved up enough frequent flyer miles for a free ticket to anywhere you want to go in the United States. Nice work. Most people who remember to put their frequent flyer number into the box before departure forget about their miles and let them expire.

But you're just a couple of miles short. And you really really want to go see Aunt Ximena in Palm Springs over Labor Day. Distressed, you check the airline website and see that you can buy two thousand miles for sixty bucks. And you're so excited about In-n-Out and Aunt Ximena's Uruguyan Barbeque that you're just about to cough it up. But you shouldn't.

Hold on fellow passenger! There are ways to accrue those miles without wasting money straight from your pocketbook. At the very least you can use your money practically and earn the miles on the side. Here are a few great ways to do that.

• Check the website for promotions. Several carriers host small promos for new program members to indoctronate educate newbies on the advantages of their specific product. These change every so often, so it's helpful to go back and make sure that you've qualified for all of your excitement.
• Go shopping. Many airline programs have deals with an online (or in air) mall that let you purchase goods from a regular retailer (GAP, Home Depot, etc) and earn miles per each dollar spent. So if you needed to buy dog food for Fido or flowers for your mother anyway, you can get 5 miles / dollar online at petsmart or 10 miles / dollar at FTD.com. Not all of them mark up goods either -- most gateways go directly to the vendor website.
  
• Go out to eat. Sites like Dining for Miles let you enroll your favorite credit card or visa/MC debit card in a program that earns miles per dollar spent at a restaurant. You can peruse about to see if any of the restaurants are near you, then next time you're out to lunch with co-workers, pick up the bill and take cash from everyone else.
• Transfer miles from another program. Points.com gives you a pretty serious shaft when transferring miles among programs (I equate them to the TravelEx money exchange in the airport), but they're good if you're in a pinch and haven't got a ton of spare cash. There are too many participants to list them all, so check the website and see if your favorite points program is listed.

Even though I'm disappointed that the Electric Map is gone, the new National Park Service's 's visitor center in Gettysburg where the map used to be does sound wonderful.

Called Gettysburg Museum of the American Civil War, it is filled with artifacts, interactive displays, a gift shop and a place to buy Civil War era food like hardtack, a type of biscuit that keeps forever.

As mentioned in a previous post, the Electric Map has been traded for a movie, A New Birth of Freedom. Narrated by Morgan Freeman, it outlines the importance of the Battle at Gettysburg and pertinent details about the Civil War. The rest of the museum is made up of galleries with different themes.

The Voices of the Campaign Theater in Gallery 5 seems like a section not to miss. This is where you can hear audio versions of letters, diaries and newspaper articles from the time period. Artifacts of note in this gallery are Robert E. Lee's stove and other items of an officer's field camp. The display is made to look like what a field camp would actually look like. The field desk that Lee might have used at Gettysburg is also here.

The 11 other galleries are as detailed, and each have a theme inspired by Lincoln's Gettysburg Address. For those of you watching your dollars this summer, a stop here has a price that's right. The museum is free. The movie costs $8 for adults and $6.50 for children. If you can swing it, spring for the movie because I imagine it will help highlight the sites that you'll see when you tour the actual battleground. Plus, Morgan Freeman has such a lovely voice.

From June 29 until July 6 is Heritage Days which commemorates Gettysburg's history. This year the museum is playing host. Here's a link to the schedule of events.

Gas prices aren't the only expense of a vacation that pinch the finances. Admission fees can be a real downer. If one is traveling with young children, huge, expensive museums can be overwhelming.

These are two reasons why the National Aquarium in Washington, D.C. sounds appealing to me.

At $5 for adults, and $2.50 for children, the admission is not even close to the $18.75 amount for adults to the Newport Aquarium in Newport, Kentucky. The Newport Aquarium, the last one I visited, is quite impressive, but sometimes I'd rather opt for a simpler venue for less money.

Last year, when we went to the Smithsonian National Museum of Natural History, much of our time was spent finding a bathroom and each other. Due to time constraints, we hurried through sections where I wanted to linger. When mixing children with large museums, it's often necessary to leave out entire exhibits in order to not have a kid meltdown halfway through.

With a smaller museum, like the National Aquarium that claims you can see the whole thing in 45 minutes, you don't have to pick and chose among options. At the end of an hour you can end up at the gift shop satisfied and have time and energy left to take in something else close by. I'd head to the outdoor sculpture garden at the National Gallery of Art for starters.

Along with the aquarium's renovations that include new signage, carpeting and exhibits is a new theme--"America's Aquatic Treasures." Look for alligators, eels, sea horses, a baby loggerhead turtle and more. [see Washington Post article]

If you can make here on August 9, it's Shark Day. There are several activities geared towards kids and talks adults would enjoy.
