But I'm confused - how can you all be on the same PNR if 2 of you are flying from GLA and 2 from LHR. Everybody on one PNR must have the same itinerary.

I am going to purchase a GLA-LHR return flight for my wife and myself (I didn't want to purchase it until I was sure I could do this first), and when I get to GLA, ask the check-in person to check our bags all the way through to SFO.
Would that be OK?
