Booking Tips for September Travel
Book 6–10 weeks in advance

Fly Tuesday or Wednesday
Mid-week departures consistently cost less than weekend flights. If you can fly out Tuesday or Wednesday and return Thursday or Sunday, you'll often save $50–200 compared to Friday–Monday travel.
Set a price alert, stop checking manually
Prices change hundreds of times per day. Instead of checking booking sites repeatedly, set a Wildly alert for your target route and price. We'll text you the moment fares drop to your threshold.
