Anecdotally every time I would fly between SEA and JFK I was always sitting next to diamonds in C+ who worked for big tech and were frequent commuters between the cities. I expect a lot of this demand is pretty flat right now, same with SEA/SFO etc.

I really wonder if DL has a long-term play here - SEA is just not that well-placed geographically and will never be what SFO is for UA, and the local market is not going to switch away from using Alaska in my experience. Personally, with AS status matching aggressively and being part of OW I am strongly considering switching over. Now that I can earn AS miles/status for flying BA to LHR and JAL to Asia the DL draw for international travelers seems a bit less. When half of the flights I want to take are nonstop on AS compared to either 1+ stops or impossible (SBP!) one starts to wonder how they're going to compete.
