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 Knoxville to Las Vegas 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. On this route that covers United, American, Southwest 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.

How we checked

On Oct 28, 2026, Axel priced round trips from TYS to LAS for one adult in economy: 2 Tuesday and 2 Saturday departures with returns 7 days later, 1 Wednesday and 1 Tuesday departures with returns 4 days later and 2 Friday and 1 Thursday departures with returns 3 days later, November 2026 to June 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 · ≤7h out / ≤7h 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.
