Extend a rental

Before pick-up, you can move the confirmed return date online by up to 28 days from its current date, subject to vehicle availability and the updated price shown before confirmation. Once the rental has started, it cannot be extended online; contact ETERNAL and wait for written approval.

Before pick-up

1. Open "Manage bookings" in the header of the ETERNAL website
2. Select the upcoming confirmed reservation
3. Choose a new return date and review availability and the complete updated price
4. Confirm the change and keep the updated confirmation email

The 28-day online limit

The self-service change can move the return date by no more than 28 days from the return date currently stored on the reservation. Contact ETERNAL for a longer period; do not create an overlapping booking or keep the vehicle without written confirmation.

Extension not working?

Two common reasons:

• The car is already booked: another customer has a reservation for those dates, so your new return date is not available
• The rental has already started: active rentals cannot be changed online, so contact ETERNAL for written approval
• The requested return date is more than 28 days after the currently confirmed date

When is an additional day charged?

All rentals are calculated on a 24-hour billing cycle:

• Pick up at 12:00 on day one and return at 12:00 on day two → 1 day charged
• Return at 13:00 on day two → an additional day is charged

This keeps your billing transparent and easy to follow.

Next step

Change an upcoming reservation under "Manage bookings". For an active rental, contact ETERNAL before the agreed return time.

If a pre-pick-up return-date change does not go through under "Manage bookings", it is usually caused by one of the reasons below.

Common reasons

• The car is already booked for those dates by another customer
• The rental has already started, so self-service changes are locked
• The requested date is more than 28 days after the currently confirmed return date

Quick fixes

• Try a shorter extension — the car may be free for part of the period you wanted
• Contact ETERNAL if you need more than the online 28-day change window
• For an active rental, contact us before the agreed return time and wait for written confirmation

A pre-pick-up return-date change is recalculated using the current duration and applicable catalogue pricing. The complete updated price is shown before you confirm, and the updated confirmation controls.

How it is billed

For an active rental, contact ETERNAL for availability, written approval and the applicable price before the agreed return time.

Next step

For an upcoming reservation, check the recalculated price under "Manage bookings". For an active rental, contact ETERNAL.
