Michael, Aug 2026

The ac must have died, it was way to hot on this flight. Boarding g was chaotic. The flight was delayed for boarding. Not a great experience.

4.0 Mediocre

Terry L, Aug 2026

Delta continues to decline. This was international flight with paid meals & minimal knacks. All drinks were served in paper coffee cups including wine & bee that was purchased, The bathrooms were not cleaned & maintained. Trash container was overfilled with no placed to dispose paper towels. The flight arrived safely. That counts.

8.0 Very good

Michael, Jul 2026

Comfortable seats. Nice service online. Short flight, so not a lot of time to enjoy.

2.0 Poor

Aidan, Jul 2026

Awful. There was an unexpected delay of nearly three hours because there were not enough flight attendants. I understand this is likely due to FAA regulations; but in that case, Delta should coordinate with smaller airports such as RDU to have extra flight attendants on the ground and "on call". In addition, this was the second 2-hour+ delay to Boston on this route in one week.

8.0 Very good

Mary Elizabeth, Jul 2026

It was strange that the flight attendant was so adamant about having phones turned to airplane mode that he was calling out names from networks shown and waiting until they were all gone. I've never experienced that before, and after already working through an hour+ delay, it felt tone deaf. I take dozens of flights per year and have never experienced anything similar.
