However I was wondering if there is a protocol to politely ask Mr/Ms 1K whether they would be willing to swap to 3K to allow us to sit beside each other? Should we ask the lounge staff if they'd be willing to ask, or ask on board as we arrive on the plane? I'd hate to put Mr/Ms 1K on the spot directly as I feel its unfair on them (i.e. asking them when I'm sitting in 1A and they're already settled in 1K), but if there is a way to ask them quietly where its less awkward if they say no I would prefer that. If they prefer 1K thats not a problem, but they might not be bothered where they sit.
Ask the person next to 3K if he or she would like your 1A.
If you would not be willing to make that sacrifice then dont ask anyone else the same?
