Cal retired their 767-200 fleet. All other retirements have been from the Ual side.
Here is the fleet count on the date the merger was announced. . .
Cal
Ual
I don't know what the latest count is, but the only planes that are planned to be kept from the UAL side are teh 767 DOM planes that have been converted to 2 class 767 international planes and the 757 PS planes to which one has been added. So in all the UAL fleet will be retired except for 28 planes all of which have winglets and half of which have speed tape on the PFD (Primary Flight Display). None of the planes to be retired have winglets.
Probably doesn't answer your question, but there it is . . .
