Good person to ask about "life at Go" would be Crashdive - he voted with his feet and went to BWA - hear he's loving it there.
Hamroll is right, if you want lifestyle, don't work for a low cost airline, especially Go, who combine the worst of both worlds - long days and night flights, all mixed up together, so by the end of an average (18 sector) week, you won't know your arse from your elbow!
In addition, Ed Winter, Go's Chief Operating Officer has steadfastly refused to attend BALPA union meetings, to the extent that Chris Darke has, I believe, recently had a crisis meeting to force him to the negotiating table.
Since the recent MBO, Go are under even more pressure to make money, and one or two worrying trends eg the recent withdrawal without consultation of various allowances, and possible introduction of new lower pay scales for new entrants are all "negatives" from a flight crew point of view.
Sure, Go have introduced a share option scheme, but on a much reduced value to new entrants, which might be worth diddly in three year's time anyway.
To all aspirants I would say if you need hours, then you'll get them aplenty at Go, but if you want lifestyle then look elsewhere.
