The American carriers (UA and DL) are doing pretty bad, not surprisingly BR does the best everywhere. Tbh though, SEA is at healthy levels outside of DL's 50% load factors (according to A.net DL has very high premium load factors though, with economy being mostly empty, so perhaps it could workout?). CI being weaker than JX at SFO/LAX is interesting, I guess they're having a hard time shaking off their image of being the lesser carrier.

UA may have to limit capacity at 10x weekly or even go back down to 1x daily SFO after winter.

According to Aeroroutes, SEA is supposed to go daily on March 1st, but I only see it loaded up to 3/29, and then it goes back down to 3x weekly.
