JetBlue Customer Service Is Top Notch. On my first time flying them to San Fran I was offered an upgrade due to unruly drunk Russians seated next to me & a few years back on a trip to NYC from Orlando my girlfriend and I were bumped from our original flight due to an earlier cancelation, we got seats on a later flight & then offered a 100 voucher for future travel, not to mention that flight was 1/2 full. Delta is the best, exemplary service. My flights to & from Greece were exceptional.
