I will be flying on Lufthansa and the policy is check-in opens 23 hours prior to the flight. However, I went to familiarise myself with the procedure and found that I could access and do online check-in even though it's more than 23 hours prior to the flight.
I would like to know if the airline will still consider my check-in to be valid. Or would I have to do check-in again when the official period starts?
When I check in online it shows as “already checked in” and the boarding pass is available.
(No bags to check in just a carry on. It’s at Singapore’a Changi airport).
