You haven't seen the route maps. There is very little overlap.
I haven't seen the routemaps?
Who are you, my guardian angel?
I have seen them.
Look, I'm not saying that individual routes overlap. They don't. But I just see a lot of areas where there is a lot of overlapping service within the region. i.e. if someone wants to fly on Merged-US-AA from IAH to LHR, do they need connecting options in ORD, JFK, PHL, MIA, and CLT? That can be consolidated. Look at what DL has done with MEM and CVG. That's all my point is.
I think pilot career progression would be much better at each carrier if there were no merge.
