Can you fly to Georgia with a different passport than the one used to book the ticket?

According to border control (phone inquiry): show the airline the old passport matching the ticket, and present the new passport at border control. No ticket changes are needed.

Some border officers stamp not only the passport but also the ticket itself — worth keeping in mind when using different documents at different stages of the journey.

At your destination you must show the same passport used at departure. Mixing passports at different stages of the journey is not advisable.

If you hold two valid passports, you may show the second one to border control only if questions arise — but the passport used for boarding and entry must match the one on the ticket.

Airlines (such as Red Wings) officially do not allow boarding with a passport different from the one on the ticket. A mismatch is grounds for being denied boarding.

The safest option when holding two passports: either update the ticket to reflect the correct passport, or simply fly using the passport already listed on the ticket.

Border control at the destination may not always check which specific passport you present, but this is unpredictable. The key condition: the passport shown should not contain stamps that could raise concerns.
