Differences is one week of ground school M-F. Then 2 sims a MV, a Loft and LOE. So 5 Sims total, probably w/ a couple days off in between there. 2-3 weeks. Its not too bad and the 70/90 captains in all honesty have been some of the best I've flown with. You'll get a couple that are a little strange, but the crews in general are just better in my opinion. And if the gate agents say they don't like some of our captains, thats fine I'm sure most the pilots don't like all the gate agents. I've had mine experience trying to explain to one of them what positive space means.
