Why book with Axel?

  • Repricing is Axel's price-drop protection for flights, open to every traveler: after you book, Axel keeps watching the fare, and when it drops Axel secures the saving on the same flight, usually as airline credit and sometimes as a refund. It is never guaranteed. Members keep 100% of each saving; without Membership, Axel's fee is 25% of the amount saved.
  • Axel charges no booking fees, and the price you see includes taxes. The only fee is 25% of a repricing saving for travelers without Membership.
  • Axel is free to use. No membership is required to search, book, or get help from Axel.
  • Axel Membership is optional. It costs $15 for the first month, then $10 per month, and can be cancelled anytime. Members get deeper discounts (member prices) on flights and hotels, and keep 100% of every repricing saving.
  • Already booked Idaho Falls to Denver somewhere else? Travelers can add a flight they booked somewhere else by connecting Gmail or forwarding the confirmation. Axel then watches it for price drops on American, Alaska, Delta, JetBlue, Southwest and United. Basic Economy and award tickets cannot be repriced. That covers every airline in these examples (United and Delta).
  • Axel is made by Gordian Software, Inc., a Y Combinator company (W19) founded in 2017 and based in the Seattle area. The company is led by CEO Stephen Grabowski, formerly of Skyscanner.

  • 2027-09-11–2027-09-18 (return 7 days later): $368.77 United Airlines (out IDA–DEN 4787 17:57–19:40, back DEN–IDA 2814 11:50–13:33; nonstop out, nonstop back). Checked 2026-10-28T23:47:05Z.

How we checked

On Oct 28, 2026, Axel priced round trips from IDA to DEN for one adult in economy: 1 Saturday departure with returns 14 days later, 12 Saturday and 2 Tuesday departures with returns 7 days later, 1 Wednesday, 1 Friday and 1 Thursday departures with returns 4 days later and 5 Friday and 1 Thursday departures with returns 3 days later, November 2026 to September 2027. Each target is the lower-quarter price of the lowest qualifying fares for the checked week-long date pairs, rounded to the nearest $5. The midpoint is their median; neither is a historical market average. Shorter travel days means same-day arrivals · ≤1 stop · ≤4h out / ≤4h back. Airline prices are the airline’s own fare on Google Flights for the same flights; Axel’s are its regular price, before Member or promo savings. This is a snapshot, not a forecast.
