I just interviewed on recently and here's the info I got:
Insurance is same as NWA employees get. BC&BS with employee contribution $295/mo for entire family, down to $90/mo for just yourself. Dental, Life Insurance, AD&D, LTD is also available. Benefits are available 30 days after your hire date.
Travel is available immediately on NWA for you and family, DL benefits start after six months employment. From what I gathered you travel free on NWA unless its first class. Sounds like they have several interline (ZED, ID90, etc) agreements available as well.
13 days of vacation are accrued your first year.
Training pay is as follows. 15hrs for completing the homestudy, paid 3-1/2 hrs per day for indoc in MSP, then min monthly guarantee+24hrs/day per diem for the month in YUL. I did the math and that comes out to around $2900 for the entire training event.
