I've heard both good and bad things about Amways flight dept. The biggest downside that I've heard more than once is that it's VERY political
Had a conversation with the Chief Pilot there a few years ago and the details I got was most Gulfstream flying was to Asia and Europe, 15 days off a month, start at 75-80K till you upgrade to cpt which took about 3 months then bumped up to 85-110K, after 5 years 144K. Flight dept was around 40-50 years old and never have laid off a pilot, mins are 3000ttl ATP and a jet type.
I didn't read the article so I don't know how much differs from what I was told, and again that was like 5 years ago.
I've talked to two pilots over there....one loved it, and the other hated it.
Sounds like any flying job out there.
