Insights shared by verified travelers who flew the route from John F Kennedy Intl to Seattle 
SarahFlew with Delta-Jun 2026
Delta had a very organized boarding process which I appreciated. The construction on the way to JFK meant my Uber had to detour through some residential areas which was annoying. I would have used the subway and AirTrain if I hadn't been traveling with my cat.
