I guess my regular use of JetBlue to fly from Nashville to JFK is not enough to keep the route profitable. The service ends on January 6. I think I’ve written here that Delta has done what it can to match the route — and under-price it. As soon as JetBlue pulls the plug, Delta will increase their price. I guess I’ll be doing the SWA Islip/LIRR thing again. Not my favorite, but by the time one hassles with Delta’s JFK operation, flying SWA into Islip is a pleasure.
