My reservation tickets (Aberdeen -London KingsX) for two window seats facing each other show the word GANGWAY - does that mean the seats are the two-seat configuration on one side of the gangway as opposed to the four-seater configuration on the opposite side of the gangway?

Just to say - sometimes you are unable to get the ticket type that you asked for. The text telling you this isn't obvious if you aren't actively checking for it.

This is especially true for long distance journeys such as Aberdeen-KGX (which is one I have done several times myself, being at university in Aberdeen).
