hi all,
quick question for someone who's familiar with the airport
I'm flying LHR-OSL on BA and a few hours later on a separate PNR i have an OSL-DOH on QR (hand luggage only)
I checked in online for the QR flight but the boarding pass is not available and it says I'll need to collect it at the airport.

Does anybody know if I really have to go through immigration and check-in / security again in OSL just to collect my boarding passes? Is there a desk where I can collect the boarding passes following 'connections'?

Or could I even get my boarding pass for OSL-DOH in LHR before my first flight?

thanks everyone
