i used to fly US occasionally through LGA when it was part of *A, and over the years i was watching the slow but gradual takeover of DL in terminal C. it's still got a long ways to go in my opinion, but it's making noticeable improvements. their waiting area has ipads where you can order food from the gate, charging stations, a new sky club, and so on. US air put in a new club in there, but their footprint there is definitely shrinking (maybe something to do with the merger, i don't know).
meanwhile, i've seen UA do squat to make things better in the wasteland that is terminal B. i don't know about profitability and such, but you can definitely notice who's investing to make things better and who's not.
