Where Can I Find Cheap Flight to Mexico?

It depends on where you’re flying from and where you’re flying to. US Airways and Alaska Airlines have lower than normal prices ($150 each way) from the western U.S. to Puerto Vallarta and Mazatlan most of the summer. With Expedia and Travelocity, also be sure to check last minute specials. Sometimes you can get a flight-hotel-car package for about the same price as you’d otherwise find for the flight alone.

Try Priceline, if you don’t mind finding out the time of your flight after you pay. I bid very low and increase it a little at a time. Of course, I’ve flown a few red-eye flights, but for very little money.
