11 Smart Moves: Cheapest Day to Fly for Christmas (And the Day to Avoid)

9. Use price trackers and flexible-search tools to catch drops

Price-alert tools are essential for holiday planning. Set fare alerts on Google Flights, airline newsletters, and third-party trackers so you receive email or mobile notifications when prices move. Flexible-date search features let you scan a full week or month to spot the cheapest departure and return combinations. When an alert shows a meaningful drop, compare it immediately to the carrier’s site; some airlines reserve the best inventory for direct-book customers. If you hold a refundable or changeable fare, you can rebook for a lower price and request a refund or credit for the difference where allowed. Track multiple routes, including nearby airports and one-stop itineraries, because the cheapest option often appears in less obvious pairings. For organized travelers, a simple spreadsheet with dates, alert screenshots, and a target price helps decide when to buy and when to wait.
