Just another comment on a Breezeway experience:

Leaving out of MCI (Kansas City) yesterday. I was zone 2 (dang it). First class boards. Zone 2 people start lining up in the breezeway so I join in the Breezeway line. Single person/stand scanning tickets.

As soon as they make the announcement for zone 2, a billion people pile into the previously unoccupied, regular (non-breezeway zone) and start boarding. The agent tries to do one from regular, then one from Breezeway, then back and forth. Doesn't seem like that's how that should work (and is typical operation in my opinion of it.)

Also, with the current overhead bin situation (ie they are cram-packed these days as passengers bring on two body bags a piece it seems to avoid fees) I don't see the advantage of strolling on the breezeway at zone 8 when there won't even be enough space for a biscoff in the over head bin, let alone a smaller carry on.
