I will be travelling with Ryanair in a few weeks. Currently I have a printer so I can do the check in and print the tickets.
I am not yet sure if I will increase the weight in my luggage. I will only know this in a few weeks and I won't have access to a printer any more.
My question is if I can add more checked in luggage after doing the on-line check-in. If yes do I have to print the ticket again?
Note: The answer from user3470 is valuable but doesn't answer my question. I plan to take only hand luggage but I might have to add checked in luggage later. As I described before, by than I won't have access to a printer. Can I still use the same "printed ticket" even if I add luggage?
