I think this was alluded to in another post, but I have found, for future travel on UA that some of the (new?) 737-800 and -900 cabins have DRASTICALLY REDUCED FIRST CLASS SEATING. I was looking on the UA website for travel to BOS from IAH in June, and MANY of the 737-800's and -900's now have just EIGHT FC seats, just like the A-319's that I thought they were phasing out. That's 8 fewer on the -800 and 12 fewer on the -900. CPU's have been few and far between even for 1K's like me for a while, but now the RPU and GPU will be essentially unattainable, with FC cabins of EIGHT seats I guess UA really doesn't care about their higher tier Mileage Plus Members after all
I have been loyal to CO/UA for over 35 years, but I fear this is the new UA. If so, it will finally be difficult for me to maintain my loyalty.
