Although you can’t change your contact details, you can add additional ones such as a secondary email address or phone number. Just sign in to your account, go to your trip, and scroll to the My contact details section. Click Add contact details, and from there you can add and save any items.
Please be sure to edit your details through your Kiwi.com account. If you try to change your details through the carrier directly, we won’t be able to contact you with updates regarding your booking. If you have our disruption services, this would cause you to lose the coverage they offer.
