G'day Jarse,
I believe 2018 with a 2 year extension clause.
Given I've been hearing for close to 20 years that one shouldn't join NJS/Cobham because their days with QF are numbered, I wouldn't be too worried, AS LONG AS complacency doesn't set in. Also, given that the existing 717s are being refurbished to 125 seat capacity, I don't think they're heading off shore any time in the near future.
