To those above posting re business travel: Two of the guys I meet up with quasi regularly from my high school days used to travel often for business. They miss the game of accruing and maximizing points and miles on these trips. There is a whole subset of folks apparently who take this extremely seriously and work the situation for max freebies, cash, and prizes.
I will say one thing. Gotta fess up here. When I flew to Austria with my Mom back in 2015 - I went to the British Airways Business Lounge that once existed at the Phoenix Airport. I was going to see what it cost to get in given that we had steerage class tickets. They let us in for free!!! Seriously. I very much enjoyed it and can understand why this is a sought after perk.
Upscale appetizers and BOMBAY SAPPHIRE for g and t's instead of a cheap well gin? I'd be on it too if I could get it. Rob
