I'm not knocking Xjt, their training is very good don't get me wrong, but I found the training to be the same if not a little bit better at RAH.
Training at both companies is through Flight Safety which is very good. The biggest difference between the two companies was the pace, and expectation level. At XJT, I believe I got 12-15 sims (I forget since it was years ago but I remember they gave us a lot) and they spoon feed the weak to get them through, RAH you were given 10 sims (maybe less can't remember)..they would give you one or two more if you really needed it but it wasn't a given, a few guys in my class didn't make it.
Like I said, I'm not knocking Xjt, it was very good training, but very comparible to the training I received elsewhere almost identical since its flight safety. It comes down to how many extra sims you get to let that info set it.
And yes it is true United hires a buttload or Xjt pilots...
