Nice to see you and others turning up here to "warn" people, but, um, maybe you could be a little more accurate.

What you're really describing is DHL, not Amazon. Certainly you name some airlines that fly for DHL, not Amazon. DHL uses numerous carriers in the US. Amazon until now contracted with exactly two (and those two in turn allocated aircraft between their two airlines).

DHL used to be the bugaboo but now it's "evil Amazon", because it makes a better propaganda target.

Amazon currently uses ABX for six (7 in a pinch) aircraft. If ABX fixed its toxic labor environment, it could fly many more. They're an excellent pilot group and they're not being handled well by their managers. Their problems predated Amazon, their pre-Amazon contraction was being caused by DHL pulling down frame after frame after frame because they really-disliked ABX and its management. Amazon was a potential golden goose, but got caught in the toxic labor mess.

Amazon uses Atlas for 17, down from 20, 767s. Atlas also flies extensively for DHL, the Military, Boeing, and any number of ACMI customers. Amazon is only a part of Atlas's extensive business. Atlas's problems are Atlas-made, pure and simple. It is another company that could fix its labor issues pretty-quickly if it brought in new leadership, and could reap substantial benefits in the form of new business. Amazon didn't cause Atlas's troubles -- Atlas's nitwit management did. And all of this applies to Southern as well. God only knows what will happen when the NTSB finally issues its report on Houston; I think it's remarkable that little has been done in terms of formal safety activity given that management has to know what's coming, and I take this as another example of deficient management. I truly hope that Atlas's shareholders give the dopes the heave-ho soon, and bring in someone who knows how to lead and inspire, fixes all the little annoyances their pilots experience (like scheduling/hotels, etc. -- something other airlines seem to be able to handle), and work on creating a solid new contract. Amazon is actually helping to put pressure on AAWW management by pulling airframes due to their inability to perform adquately (2 767s so far, and the 10 737-800s that will now be going to Sun Country).

Cargojet and Mesa, airlines that you mentioned, don't fly for Amazon. Cargojet flies now for DHL. Mesa was rumoured to be taking the DHL 737-400s from Southern, because they can't staff them plus the 5 Amazon 737-800s they agreed to take. But I haven't seen anything official yet, and it ain't done until it's done.

In contrast, ATI, which has good labor relations (to the dismay of a lot of pilots at other ACMI carriers) has grown from basically 8 aircraft allocated equally between DHL and the Air Mobility Command to 35 aircraft (27 767s and 8 757s) in a short period of time, with at least 4 more 767-300s coming next year. They generally treat their pilots with respect and make them feel valued; people don't hate coming to work. They are able to hire pilots even though many people try to tell them how crappy their contract is. They place a big value on personality and have the luxury of doing so. Expansion gives a lot of opportunity to upgrade, which is for now a nice benefit.

How the addition of the Amazon 737-800s goes at Sunny is going to depend entirely on how well management works with its pilots and others to get most people pulling in the same direction. Money may be a part of it, but I'm here to tell you that lots of us trade some money every day in order to have a work environment that we like, or at least don't hate.
