Just to clarify since I said something about confrontation...it isn't that I don't mind using the breezeway to board ahead of the general line, it's just that I want the process to work ideally. Maybe this is because I look young, but sometimes (and thankfully it really is pretty rare) I won't be acknowledged the same way as a typical Medallion/FF. And I'd rather not have to stand at the breezeway and clear my throat or reach over other passengers.
Will I still do it? If I need to, yes. Maybe Delta staff and passengers just need time to get used to it because it seems like it runs pretty smoothly with CO.
