FWIW, the 'Breezeway' concept doesn't work at any airline. I've been with CO for years - they were the first airline I flew that started such a concept...seems after they started I noticed that many others picked it up. It's never worked for them and I see this and such efforts as huge wastes of money (signage, carpets, etc). One of the main reasons it doesn;t work (besides casual travelers ignoring it) is that there still is only one GA taking the BPs at the gate - it's difficult for them and extremely annoying for custoemrs in the non-Breezway line if the GA keeps stopping the regular line to go to the stroling up Breezeway customer. I find they are not apt to do this and I don't blame them in a way (think flight crews cutting through security lines). IMO, they should just drop it period. Board by zone - if you miss the Zone 1 call then you just got to wait in line...not really that big of a deal
