Well, what kind of job are you applying for? I'll answer from a Ramp/Gate agent perspective, but know that if you're applying for a corporate position you might get different benefits.
Standard airline travel benefits--expect this from all airlines: Unrestricted free online travel (a couple make you pay something like $10 per leg), steep discount standby travel on other carriers (AC participates in the ZED program http://www.gozed.com/discounts/home.cfm
- I fly on ZED coupons a LOT, great way to get around Europe), the ability to upgrade to F/C/J class for a small charge (my employer charges $20, $100 for transatlantic, not sure about AC
). You won't be able to fly on all Star carriers though--United doesn't even have a ZED program. Also, most stations have a few independent agreements (especially outstations), check with your new boss if you get the job. Don't bring up travel benefits too much though--it's sort of a turn off to know that an employee is only working for you to fly for free. Also your wife and kids if any can fly, domestic partner if you've got one, and if not, you might get to pick a companion but that policy is so different from one airline to another that I can't say for sure. You'll probably also get a number of buddy passes.
Just stick to your qualifications and past experience, don't speculate about the job or ask a million questions.
