OLCI & Bulkhead Seat

Was wondering if someone could give me a quick answer. If I were to check in online and print out my boarding pass, would I be able to ask the bag drop off desk to perhaps give me a bulkhead seat or will they outrightedly refuse to do so based upon my having already checked in online?

You can ask for a change of seats when you are at the bag drop desk.

OLCI is a good back up in case the seats you wanted are not available, at least you will have a seat you have pre selected and are happy with.

My suggestion to get a bulkhead seat is to use the twilight check in service if it is available from your departure airport.
