I usually would fly out of LHR, but there are no confirmable upgrades on CO. So I am taking a scenic route.
I can either fly out of GLA, EDI, or BHX. All have upgradable space. Of the tree, which would be the best overall experience?
I care about:
1. A good lounge (not a fan of contract lounges. I believe of the three, only EDI has a *Alliance affiliated lounge, operated by BMI)
2. Nice shopping. LHR, of course, has the best. How do the others fare?
3. Pleasant terminal. I don't need new and fancy. In fact, I prefer vintage architecture. But I don't want gritty either!
4. Walkability to a good airport hotel.
