Spunky little USA3000 (877/872-3000; is having a sale to Cancun. This of course is guerilla marketing at its finest. But the $1 fares actually do exist, and USA3000 has an excellent flexible date search calendar that shows you exactly when they're available. The $1 fares are good only for outbound flights, but you'll still save money even though the return flights are much higher, typically $199 one-way.

For example, looking at Cincinnati to Cancun leaving on March 5 and returning on March 12 the total fare is $292 round-trip including taxes on USA3000, vs. a next lowest of $582 RT on Continental or a whopping $929 on Delta.

From Philadelphia leaving March 9 and returning March 16, the same $292 RT on USA3000 vs. $498 next lowest on American. So gimmick or not, you'll save money with this sale!
