Lower Airfare Near the Witching Hour?

Totally in the experimental stage still...but for the past two-three weeks when searching for airfares, they were almost always cheaper when I looked late at night (between 9pm and 12am EST) than when I searched during the daytime at the same flights.

By waiting until nighttime to buy, the price drop was significant going from as high as $346 to as low as $211 for a one way ticket, which is obviously an even larger gap if you need two of them.  Since a lot of airlines are changing over to an equal-equal pricing system, where you even buy your round trip tickets by combining individual one-ways, it's worth thinking about this daytime vs. late night buying timetable.  So if you're searching, try it for yourselves, and let me know if you guys are getting the same results!

Inexpensive Countries for Budget Travelers

Elite Daily came out with a list of inexpensive nations for travel.  On the list:  Bolivia, Thailand, Greece, Spain, Costa Rica, Vietnam, Romania, Sri Lanka, Nepal, and Argentina.

I have heard this regarding Thailand, Bolivia and Vietnam.  I can't speak for them as I haven't been there...yet.

I lived and worked in Costa Rica and can tell you that most people might agree that it's fairly inexpensive to fly to (from the US, at least) but I think we'd argue the cost of an actual vacation there.  In fact, I often hear complaints about how expensive Costa Rica is compared to how inexpensive it's perceived to be.

I would add Peru to this list.  I found it to be a country that was much less expensive than Costa Rica with a great deal of options for travelers within the country.  I got a killer airfare mistake out of AeroMexico, so I'm sure the airfare would contribute to its being more expensive to visit, but two of us spent very little considering our 10 day trip and travel between multiple cities.

Any thoughts on the countries on the list or others you would add?
