YEP. SJS and quick upgrades.
SJS and quick upgrades? Seriously? Most of the people going are already on the 700/900. So noone is chasing a pipe dream of flying a bigger RJ. And they didn't offer upgrades to FO's. So essentially the FO's who take the contract are locking themselves into 13 more months in the right seat despite the possible upgrade in the next year here at home.
The fact of the matter is this is a completely different model and set up vs. your standard contract job. Like 79% said, name another contract where you can accrue seniority, vacation, and sick time at your home carrier while you're gone. It's the ultimate insurance policy.
