Wait for the Best Deals. The best deals on summer airline tickets are historically offered approximately 3 1/2 months before a departure date, as airlines attempt to determine their demand for summer travel, reports Rick Seaney at Fare Compare.
Check available tickets 8-10 weeks before your departure. If the flights arenât too booked, wait until six weeks prior. At six weeks: If the price looks good, go ahead and book. If the tickets look a little high but your flight is pretty full, buy anyway because fares will probably only go up. If the price is high and your flight is pretty empty, you can choose to wait a week or two to see if prices decrease.
