Booking Affordable Last-Minute Flights

Booking close to departure puts you past the point where fares are usually lowest, so flexibility is what saves money: on dates, airports and even destination. Add bag fees to the fare and check entry rules before you pay.

Depends on the destination; always verify entry requirements before finalizing payment.

Step by step

  1. Don't waste time on incognito mode

    Your browsing history doesn't set the fare. A 2014 study that queried 25 airlines twice a day for three weeks found no evidence of systematic price discrimination, and a 2021 study of Alitalia, Ryanair and Lufthansa found that people with the airline's cookie saw exactly the same prices as first-time visitors. One common reason a fare jumps is that the cheapest fare class has sold out. Incognito mode won't bring it back.

  2. Use 'Everywhere' search tools

    Skyscanner and Google Flights both let you search without a fixed destination. If you're flexible about where you go, start there.

  3. Check regional airports

    Check secondary airports near your destination and add up the full cost: the fare, bags and the train or bus into town.

  4. Monitor for 24-hour windows

    Set a price alert, but don't wait long for a drop.

Questions people ask

Is it true that flights are cheapest on Tuesdays?

This is largely a myth. Prices fluctuate based on airline demand algorithms, not the day of the week you hit the 'book' button.

Should I wait until the day before for a cheaper fare?

Usually not. In Google's data, fares were lowest on average weeks before departure, so waiting for a last-minute drop is a gamble.

Notes
Add bag and seat fees to the fare before you compare.

Packing

  • A bag that fits your airline's free personal-item size
  • A portable luggage scale to ensure you don't hit overweight baggage fees at the gate.
  • A universal travel adapter, as you may be flying into a destination you hadn't planned for.
