How to Get the Best Cyber Monday Flight Deals
Cyber Monday Is December 1 — Act Fast
Cyber Monday falls on Monday, December 1. Most airline Cyber Monday sales go live at midnight and expire within 24–48 hours. Have your travel dates and destinations ready before the sale starts.
Cyber Monday Deals Are Best for January–March Travel
Airline Cyber Monday sales typically focus on January, February, and early March travel — after the Christmas holidays and before spring break. If you're flexible about when you travel, early is the sweet spot for Cyber Monday flight savings.
Compare Cyber Monday Fares vs. Black Friday Sales
Airline Black Friday sales (the Friday before Cyber Monday) often have equal or better deals. Compare both events — sometimes the Black Friday sale lingers through Cyber Monday with identical pricing, while other times Cyber Monday offers a distinct, better set of routes.
Book Both Legs Before the Sale Expires
Cyber Monday airline sales typically expire within 24–48 hours and have blackout dates. Once you find a deal, book immediately — don't wait to compare across multiple days. Cyber Monday fares are not guaranteed to be available the next morning.

Frequently Asked Questions
Everything you need to know about Cyber Monday airline sales and flight deals
When is Cyber Monday?
Cyber Monday always falls on the Monday after Thanksgiving, the first Monday in December.
Do airlines have Cyber Monday flight deals?
Yes — most major US airlines run Cyber Monday flight sales, including Delta, United, American Airlines, Southwest, JetBlue, Spirit, Frontier, and Alaska Airlines. Deals typically include discounted published fares on select routes and loyalty program award reductions. Sales typically go live at midnight and run for 24–72 hours.
Are Cyber Monday flight deals better than Black Friday deals?
Both events offer comparable airline deals — airlines often extend their Black Friday sales through Cyber Monday, or launch fresh Cyber Monday-specific offers. The best strategy is to monitor deals across both days and compare. FareOptic tracks live fares during both sales so you can see which deals represent genuine savings.
What is the best travel period for Cyber Monday flight deals?
Cyber Monday airline sales typically cover January, February, and early March travel — the quietest booking period of the year. This makes Cyber Monday an excellent opportunity to book winter sun escapes, Caribbean trips, and European travel at the year's lowest prices.
How do I make sure I don't miss the Cyber Monday airline sale?
Sign up for airline email newsletters and FareOptic alerts before Cyber Monday. Sales go live at midnight and the best routes sell out within hours. Having your preferred travel dates and backup dates prepared means you can book quickly when the sale opens.
Do international airlines run Cyber Monday sales?
Some international airlines — including Emirates, Lufthansa, British Airways, Air France, and KLM — run Cyber Monday promotions targeting North American markets. These can include significant Business Class discounts for transatlantic and long-haul travel.
