Oh, I agree. I thought the routes were just announced for JFK-SF/LA for right now. Boston-SF/LA seems like would be the next expansion step, if the JFK routes go well. I do wonder if they will introduce it on flights like BOS-Seattle, BOS-Las Vegas
I wouldn't count on Boston-Seattle and Vegas. I could see NY-Seattle being marginally viable but I wouldn't say the odds are very high. Another thing to note, from something I read earlier, they only have about 12 of the 2-class A321's coming so they might only be able to get away with NY-LA/SF. The next logical route would be Boston-SF but depending on the frequencies, they might not have the equipment.
