UA does the same
No miles on Delta vs full miles on AA.No EQMs on Delta vs full loyalty points on AA.AA allows elites to select MCE seats on BE.AA allows comp upgrades on BE.AA allows 500 milers on BE.AA allows SWUs on BE.
AA basic economy is 2 points per dollar instead of 5 I believe and multipliers for status are based off the 2 points, not the 5. Still better than any other airline, but its not the full 5 IIRC
