I said before the Company wants the 190 in PHX. That does not mean they would have to move 190s from the East, but opens up possibilities of other aircraft being acquired and put there. I take as fact that the 190 counts towards min block hours West in the MOU. The MOU also will allow the mixing of metal. I now understand they can mix Check airman. For example a West C/A could give an East pilot a check and vice versa. No problem there at all, at least for me. What concerns me is I now hear (and this is rumor only) that the Company believes they can mix and match East and West pilots. The bidding systems really do not promote that, but what if a West crew member calls in sick in CLT, they put an East pilot in the seat to replace him? No problems seen in my cockpit, it would be non-issue to me, and that does not mean I accept it is legal under the MOU. I simply don't know. But there will be problems. Compare and contrast. Talk amongst yourselves. 300 words or less on my desk. RR
