Working for a UK Oneworld airline I had:
* ID90 standby on any Oneworld flight
* Could buy ID90 tickets for multiple routes to my destination & return, and get a full refund for unused tickets when I got back. (We also had a BA reservations PC in our office so when it wasn't being used I could hop on and look at flights and predicted/historical loadings ;-) ).
* ZED confirmed seat with other carriers
* Applied to spouse/partner etc
Working for a US airline - also Oneworld - I have:
* Free standby travel on any company/company branded flight ie mainline + regional partners.
* 6 per year higher priority standby tickets (full route to destination, with even higher priority for connections)
* ZED standby on other carriers
* above applies to spouse/partner, kids, parents.
* Cockpit jumpseat/spare cabin seat with pretty much every US carrier.
JS priorities apply to own company, wholly owned subsidiary, contractor, or other.
I really missed staff travel in the period between UK airline and US airline employment.
