Step by step
1. Search the exact itinerary you hold: same flights, cabin and number of travelers.
2. Compare the total: miles plus taxes and fees, and any change or redeposit fee that applies to you.
3. Change the ticket on united.com or the app, or call United, and confirm the miles difference is credited back.
4. Keep watching. Prices can drop more than once before you fly.
- Official United rule
United's fees for changing or canceling award tickets depend on the ticket, your Premier status and how close you are to departure. Always check the current policy.
- TopTier estimate
TopTier only alerts you when savings pass the threshold you set, so small drops don't lead to wasted effort.
How do I catch drops without searching every day?
Add the trip to TopTier's award price tracker. It checks the booked itinerary on a regular schedule and alerts you when the price drops meaningfully. It can also flag a shorter trip that becomes available. TopTier never rebooks for you.
