• 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 Sun Valley to Cancun 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.

How we checked

On Oct 28, 2026, Axel priced round trips from SUN to CUN for one adult in economy: 1 Monday departure with returns 29 days later, 1 Saturday departure with returns 14 days later, 13 Saturday and 2 Tuesday departures with returns 7 days later, 1 Tuesday departure with returns 5 days later, 1 Tuesday, 1 Friday and 1 Thursday departures with returns 4 days later and 4 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 journeys means ≤1 stop · ≤12h out / ≤12h back; overnight arrivals allowed. 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.
