Seems like a good place to start right there. Current network planners have always hated the 752; they have stated that repeatedly. They don’t mind the 753, and the 763 has been a good LHR performer. So permanently retire at least 48 752s for starters and surplus based off of that. Throw the new MAXes on to whatever they were doing as required and if a MAX can’t do it then don’t operate the city pair.
