Oh, A is horrendous. It's old school rotunda, with too little seating and too tight a space between gates. The UA club is actually decent now, however, when it's not crowded.

The egress one-body length walkway IS a safety risk, and I'm shocked it's allowed to exist as is. I hate A with every bone in my body.

I've found the new bins a Pre in C have significantly sped up the lines. I can now jump ahead of the family of 4, and I haven't had more than a 10 minute wait in well over a month. Mornings can be heavy, but the line moves quickly now. I haven't been herded downstairs to wait in quite a while.
