1) The ability to book an award fare and paid fare in same reservation (often times my wife will accompany me on a work trip)
2) Up to 8 premium class complimentary seats at booking like United offers
3) Ability to extend elite benefits to others in your reservation by linking PNRs (United has this now and it allows me to move my family into better seats without calling the 1K desk)
4) WAY more AA inventory to book with AS miles. I don't mind even paying a premium in miles, I just want to be book RDM-PHX any time through AS website as an example
5) Include Titaniums in pre-boarding, even before first class (like United does with GS, Disability, Families with under 2, 1K, then they go to group 1 which includes first class)
