lee626 Would this affect boarding, or is it still possible to use the tickets?
Is the error on the tickets? Or on the reservation? Tickets and reservations are not the same thing. You need a ticket, but reservations are optional.
There are no pre-boarding checks, so nobody stops you from boarding even without a ticket, and probably nobody will want to see your reservations. These only come in play if someone were to already sit in your seats…
