Delta includes JFK-LAX on complimentary upgrades but with a 16-person cabin, usually no one below Diamond/Platinum will get upgraded during business hours. However, a SWU puts you at the top of the list.
DL runs 757s with Business Elite and some Economy Comfort. UA is changing to 2-cabin 757s with Business First and some E+. Right now, AA doesn't have a "Economy Plus" product on their 767s, but should when they start their A321s in the future.
Please excuse my ignorance, but could you tell me what RPUs and SWUs are?
And is there a website that breaks down all the different fare codes?
