Be Flexible
Be flexible in your travel plans in order to get the lowest fare. The best deals may be limited to travel on certain days of the week (often Tuesday through Thursday, or Friday night through Sunday morning) or particular hours of the day (e.g., late-night departures). This applies to each of your flights, not just the first flight in your itinerary.After you get a fare quote, ask the reservations agent if you could save even more by flying a day earlier or later, or by taking a different flight on the same day. Or simply ask the agent what the lowest fare is, and what you need to do to qualify for it.
Discount seats are usually "blacked out" during holiday periods. However, you might be able to get a discount fare if you fly on the holiday itself.
Plan Ahead
Plan as far ahead as you can. Most airlines set aside only a few seats on many desirable flights at the lower rates. The real best bargains often sell out very quickly. On the other hand, if a particular flight is not selling as well as expected, air carriers sometimes make more discount seats available for a particular flight just before the advance-purchase deadline expires.-
For example, if the lowest fare has a 21-day advance-purchase requirement but is sold out for most dates, and you can go any time, ask about fare availability on flights 21 or 22 days from when you call.
Compare Airports
In a large metropolitan area, the fare could depend on which airport you use.- For example, if you are going to Southeast Florida and plan to rent a car, it might not make much difference if you fly to Miami or Ft. Lauderdale, except for ticket price. Also, a connection (change of planes) or a one-stop flight is sometimes cheaper than a nonstop.
- Note that small airlines sometimes have only one flight per day in many markets, and they frequently will not reroute you on another airline if your flight is canceled or delayed. In such cases you may have to wait until the next day to fly.
