Flights from Buffalo to both Las Vegas and Phoenix are currently undergoing a large unadvertised drop on Delta. Prices look to be down about 40-45% from their usual norms.

I love it when a roundtrip flight to Central America drops into the $300s (after taxes!).

LOT Polish Airlines looks to have just dropped some of their flights to Warsaw, Poland down to 40% less than their closest competition.

Right now KLM has some of those strange fares in their system, where it's really cheap to fly out of a U.S. city and back into a Canadian one, for far cheaper than a roundtrip out of either country.

Update @ 5:23 PM : Delta seems to have caught on and the price is now back up unfortunately. There were reports that the reverse was working for a while as well (out of a Canadian city, back into a U.S. city). Could still be worth trying.

Update Sep 24 @ 2:23PM - Looks like the cheap fares to Delhi might be gone.

Aerosvit Airlines just dropped some of their prices to Moscow, Russia down to ridiculous levels. They're currently 65% cheaper than the next cheapest flights to Moscow!
