One perk for million mile status I haven't seen mentioned is the ability to get exit row seating when booking. That is a big deal to me. Also, with United, when I obtain million mile status I will be lifetime gold and my wife will get gold also. Many times we travel on slightly different itineraries so her having status will help with seat selection, baggage and check in. I traveled a lot on business before I retired so I have million mile on AA and am approaching it with United. This is my last year with any status on United so I'm trying to close the gap as much as I can this year.
