It was okay. Had a thing with the front desk, she had me repack my suitcases to have them be under the weight restrictions, but then the other one was overweight, she argued with me about it when there were tons of people in line. Wasn’t great.

Organization and the adjusted times but the snacks could be of a bigger portion

Our flight was delayed by a bit. I appreciated that we were kept informed on why periodically. Boarding was fine. I overheard one flight attendant sounding very rude to a passenger who was not paying attention to the safety demonstration. The snacks were minimal as it was a short flight. There was no entertainment. Overall the flight was good back to LGA.

All good the seats a little tight and no I pad screen

Just an evening before they canceled my ticket and offered me ticket costing 3 x times more than. I will not fall prey to these scams,Will never book through kayak now. Such a bad experience.

was okay except.. 1)the porter check in webpage doesn't let you print your boarding pass from home 2)that there was a 90 min cut off for checking in on the kiosk in general, and to print a boarding pass, even tho i checked in online already....

It was amazing although they did bump us up to the front which gave us more leg room and a meal. The service was great! The staff were friendly. :)

The flight was delayed by more than one hour. The terminal was consequently overcrowded and hot. We lost our car reservation and hit rush hour traffic in Boston, which added two hours stuck in traffic to our trip.

Lavatories broke with an hour to go. At least we were on time.

Due to mechanical problems it was delayed causing problems the actual flight. Was fune
