Got the email which explained it but I need conformation from you all. As I see this, IT IS GREAT!!!!
Ok, there are kinks (luckily from the sounds of things mostly training and branding - cheaper to fix). Outside of that, what a win win win. After all, how many times each year do you end up dashing to a gate only end up waiting to board along with what left of zones 6-8 and ALL OF ZONE 9.
I for one like boarding early to stow a bag, pull on a drink and get out of the way. When I can't make that happen, anything that gets me to the front of the line is very much an incentive to fly. Great move and yes, it is an Enhancement.
