Thanks for explaining. I understand more but just wanted to know if I can continue to expect this as every agent I talked to was surprised. Is it normal for aa that everyone who doesn't pay for specific seats has to confirm and get every boarding pass at the gate?

It's their business, they can do what they want. If this is the case I wish it was more clear about the different level of service you get when you pay for a seat. It's not only getting aisle, exit row, etc it's the ability to check in online and avoid multiple lines and have a greater percentage of flights completed? That's huge for me even if I don't care about being in the middle seat.

Thanks again, once fully informed as a consumer I'll make the choice which meets my needs.
