Yes you can, the passport information is taken mainly for the countries that you are travelling to and from (As others have said the API). If it is one of the bigger airlines go online and they will something such as a Manage My Booking section, you can update passport details there or at the airport it can be done by the check in agent.

No its not on the actual ticket. For the API. I havent received the new passport yet just trying to find out if it is possible to do.
I assume as the OP said you can change it online when you have the new number
I think they are more concerned if the PP is valid and hasn't expired
I booked our holiday flight tickets however my sons new passport will be arriving any day now. Can I change the passport number on his flight ticket? Anyone knows? Tried calling emirates but their number is busy.
Is your passport number on the ticket? I thought you only inputted that online for API?
