How to buy a last minute cheap flight
Check airline newsletters, websites that specialize in last minute air travel and the travel section of your local newspaper to find last minute deals on flights.
Sometimes you can save money by booking flights late because airlines that have not filled their planes will offer discount fares.
Compare airfares from different airlines, websites and travel agencies.
Purchasing flights directly from the airline is not always the cheapest deal, so check out a few different travel websites and travel agencies to compare prices. Search for flights during undesirable days and times.
