I'm at TSA, and overall I think flying with the CQFO's isn't a big deal. Most of them have been really good pilots, and the only real weakness I've personally encountered was that some were not 100% comfortable with the left seat because of only flying ~20% of the time as a captain. I don't think the seat switching is a good idea, personally. However, that is what our contract allows, and we aren't the only carrier that does it. But I have to imagine, that it makes things harder for the CQs that have all come from other airlines, and especially those from another airframe.

With that being said, the two worst captains I've flown with here by far were quick upgrades (7 or 8 month upgrades). I believe both of these pilots for whatever reason didn't qualify for the CQFO program. They flew a couple hundred hours at most as an FO in the 145 and then somehow passed upgrade and captian IOE. Terrible airmanship and complete lack of basic knowledge and common sense with both....

Just my 2c.
