Flying at Atlas(ACMI) is like working at any on demand 135 outfit. Except you fly big jets and the stage lengths can be 4000 miles opposed to a couple hundred. And you're gone 17 days.
Today I'm in Bahrain. Yesterday I was told I am flying to Amsterdam. Today I was told I am going to Hong Kong instead. Maybe tomorrow I will go somewhere else... but I'm fairly sure I'll be home by the 9th.
I don't fly at Atlas.
