How to correct passport details on an Etihad ticket after booking?

At online check-in you enter the passport again: another traveler confirmed in late July 2026 that Etihad online check-in asks for passport details anyway. In their experience, whatever the aggregator collected at purchase either does not show up in the Etihad booking at all or gets replaced at check-in.

What must match: according to a traveler's experience (July 2026), the key thing is that the name, surname and date of birth in the booking are correct. If the error is in one of these fields, check the correction conditions and any possible fee with Etihad or the ticket seller in advance.

Where to fix it: in late July 2026 a participant advised logging in to your account on the Etihad website, finding your booking there and correcting the details. The change is made on the airline's side, not in the account of the aggregator you bought the ticket through.

The passport at purchase is secondary: in a participant's view (July 2026), passport details are not really needed when buying an Etihad ticket — they are requested at flight check-in. So a mistake in the passport number entered at purchase can usually be fixed later.
