Sure, the return of the discounts would be nice, but I'd prefer the return of the transferable upgrade certificates. Delta used to issue a "TZ" award for reaching certain mileage levels. I enjoyed using these to upgrade coworkers or friends that I might be traveling with.

Same with the drink / headset coupons. I remember (dating myself) that a full fare coach ticket *always* had a couple of coupons with it, if they couldn't upgrade you. This can't cost a whole lot, but sure would improve the "customer satisfaction". I wonder if the airlines really care about us!
