As it turned out, 3rd Time not the charm. Even if you stick to Delta only. And "No", it's not just the weather this summer. My 3rd consecutive attempt to fly out of JFK to Sao Paulo on July 16th also failed. This one time, however, as I was part of a bigger group - Delta did offer everyone who had waited several hours past original departure time a taxi voucher, a 15 dollar meal voucher and some other "goodies" like bottle water and chips rolled out on a kart. The delay was due to a Pilot (and crew?) who was/ were apparently coming from Atlanta. The ground staff at Delta continues to be overall cordial as they rebooked me -- yet again for the 19th now. My criticism however remains. Not even a good will gesture is made to me, particularly, for all the comings and goings to airport, all the time I could not work as I keep trying to get on a plane that actually flies me to Brazil. Note (and this is a big observation) this last attempt of mine did include boarding a Delta plane 3 hours late (at 01:30am, yes am). It also included taxing around through JFK tarmac and run-ways and finally coming back to the gate to deplane. I was back home in Manhattan at 4:20 am as I did not want to wait around the long Delta lines anymore. Want to experience disrespect at its best, at one of America's "best" airlines? Book a ticket through Delta this summer.
