Biggest issue with Atlas is that you will make more money at any legacy as an FO then a capt. here at Atlas.
If you want to go visit all those great destinations that Cliff mentioned, buy a ticket and in reality most places he mentioned you probably don't want to even go to.
Although we have a contract, I think (and most Atlas pilots will agree) that a roll of one ply toilet paper has more substance then this contract. Too much ambiguous language. We hope that we can make things better next contract, but I would not hold my breath either. Top commuters plus LCC's have better contracts which will allow you to make more money and work less or if you decide to work more you will make more then working overtime here.
If you are coming from a commuter with a bad contract or low pay, this would be a nice stepping stone before you go to major.
The big items here are the fact that you don't have to worry about commuting or losing weight (lots of food on planes).
Good luck
