Proposing a car swap or a time change

Trip changes live on the trip page. A proposal lapses if it isn't answered within 24 hours.

• Swapping the car. Offer a different car of yours when the booked one can't make it. It has to be live and free for the remaining dates. The remaining days are repriced at the replacement's rates: if it costs more the renter pays the difference, if less they're refunded.
• Moving a delivery time. Shift the handoff by up to 12 hours either way. On airport pickups, a delayed flight proposes the new window for you.
• Changing the delivery address. You enter the money: no change, a charge, or a refund. If the renter asks first, you can accept, decline, or counter once with your own price.
• Early returns. If you accept an early return, you keep half the value of the unused days and the renter is refunded the rest.
