No K4, and I've read a fair amount of the threads. Plenty of friends at Atlas and WG. Many on 767 / 747 for Atlas.
Leaning towards Atlas seeing as I don't mind working extra for some pay. Probably stay until Delta or Southwest offers come (probably 5-8 years on a conservative estimate). Heavy type and international experience can never hurt.
I suppose I just don't want to go into Atlas blind and find any strongly sickening info too late. Care to hit me with some mines I'll be dodging? Besides the whipsaw and contract negotiations. If Atlas wants to keep Amazon a contract is inevitable and I imagine will be Kalitta pay at minimum for industry standard.
