Amend dates and times
You'll need to visit your Trips and bookings page. There you'll see your bookings listed in 6 blue capital letters with a date attached.
Tap on the booking you want to change and choose your option from the list that appears.
Your options will depend on your type of booking:
Free cancellation bookings
Tap 'Change dates & times' from the list and follow the prompts.
You're able to do so until midnight on the day before your booking is due to start. Making changes to your booking carries no charges, but you might need to pay extra if there's a difference in price.
If you have a Saver booking, you can't change dates and times. But you can tap 'Cancel' on the list and book again as long as you cancel by midnight on the day before your booking is due to start. Follow the prompts and continue to cancel your booking to receive a voucher which can be used to book the same product for your new dates and times.
When you make a new booking, make sure you're logged in to your account so your voucher appears.
