Frequency, yes (both EWR and JFK) but route suspension? I don't recall that.

Maybe AS and the SF Giants can have a "Win 2 Tickets To A Your Route Has Been Canceled" promotion. If the SFO AL starts accepting Priority Pass again, it will be telling. I haven't seen much local marketing in some time.

I do also wonder how much of this is not so much as the planes aren't making money but that they can make more money elsewhere.

As I'm now reminded of this song by dear departed Eddie Money ... ♫ I've got two tickets, two pair of dice. I rolled them once, my route's canceled twice ..♫
