Changing your dates, times, or pickup
How to ask for a change and what it does to your cancellation rights.
Updated October 10, 2026
Ask your host in Seifly messages
Open your trip and message your host with the change you would like. Keep the conversation in Seifly. Messages in the app are what support looks at if there is ever a disagreement.
Extending a trip
You may not keep the car past the end of the reservation unless the extension is properly approved through the Services. Keeping a car without approval can be treated as a failure to return it, and in serious cases the car can be reported to law enforcement as stolen. Ask early so your host has time to check their calendar.
Shortening a trip
Returning early does not earn a refund unless you asked to shorten the trip and the host approved it before you returned.
What a change does to the free-cancellation clock
Changing your dates or times does not restart the free-cancellation period. The free-cancellation deadline stays tied to your original booking and original start time.
