Just saw something interesting in the last few days.

I don't think this is a certain sign for SKW, but United is turning gates 69 and 70 in SFO into Express gates. The last trip I was on, the Bro was using 71 exclusively and they were putting 200s at 69 and 70. They've cut out little portions of the jetbridge to fit the RJ steps and they installed those absurd yellow railings to guide the cattle into the cave.

I don't think this is definitely for a huge SKW 700 expansion, but with all those 737s being retired I think many of the UAX carriers will see an increase in flying.
