Airlines are like professional sports teams: They are copycats.
Case in point: After JetBlue got plenty of attention for its $14US San Francisco to New York one way fare, Spirit Airlines announced $18US ROUND TRIP fares mostly from Fort Lauderdale, Florida to destinations like Jamaica, The Dominican Republic and Nicaragua.
But by the time most of us hear about these fares, they are gone. What to do?
Sign up for sites like TravelZoo and SmarterTravel, which get the best deals sent to them by the airlines, hotels and travel agencies themselves.
If you have a favorite airline, or know an airline flies the route you may be traveling on in the future, sign up for their email alerts. Many airlines also use twitter and blogs to get the word about their special airfares.
