Not most, unfortunately--very few. Actually, just one: DL.

International upgrades (except for perhaps the odd op-up, since you're [just barely] ahead of the non-status folk on the plane) are never going to happen on DL with AS status, but you should be able to select premium seats (exit rows, bulkheads, etc) and have some sort of priority in irrops situations.

Great airline and good program, but probably not a super fit for someone in your situation (where you could possibly get and have use for elite status on an airline you're actually flying).
