Thanks, bingocallerb22 ... hadn't come across this news yet. Interesting that the preferred seats will only be available free of charge to Comodoro (Emerald) members, but not Premium Silver (Sapphire) members, given that AA extends complimentary access to their Main Cabin Extra seats to OW Emerald and Sapphire members.
Has LAN upgraded the value of these first rows of the economy cabin with greater seat pitch, or any other benefits, other than simply being at the front of the cabin?
