FlexTrip Alerts vs Hopper
Hopper is built for phones and buy/wait predictions. FlexTrip Alerts is built for repeat routes and real constraints—like flexible date windows and specific duration of stay.
Choose FlexTrip Alerts when…
- You want email alerts in a browser — no app required
- Visit windows and duration of stay are non-negotiable
- You need a strict price ceiling
- Layover length or direct flights matter
Choose Hopper when…
- You prefer push notifications on your phone
- Buy/wait guidance matters more than trip constraints
- You are happy booking inside the app
- You want Price Freeze for a specific fare
