I’ll admit this is probably an old fashioned “lived the dream” POV but given the flux in the industry I’d suggest to the OP that it is a bit optimistic trying to finesse one’s choice of employer based on their current bases....it would certainly be well down my list of desirable criteria, certainly below the likes of “are they actually employing anybody”, “how much do they pay”..etc....
Actually as has been mentioned BA is a classic example. It had a popular base there for years...not any more...
