Jim, Oct 2026

My flight was so delayed I would’ve missed my connection and had to cancel my trip

2.0 Poor

Clyde, Oct 2026

Seemingly unnecessary delays were compounded by a lack of communication from the flight crew which turned a four hour delay into an overly stressful experience.

8.0 Very good

David, Oct 2026

I like Delta. I dislike the volume of announcements from the crew. They are not always easy to hear and typically repetitive.

8.0 Very good

David, Oct 2026

I think the crew makes way too many announcements that are: 1) hard to hear in some cases and 2) repetitive. This detracts from entertainment and concentration if working or reading.

10.0 Wonderful

Timothy, Oct 2026

Everything was great. The only thing that wasn’t was the breakfast calzone which was basically warm bread. It was very tasteless and wasn’t good at all

8.0 Very good

Michael, Oct 2026

Great crew. Comfortable seating. Nice overhead bin space. My app didn't allow me to check in for my flight to BOS. When I called Support, they didn't fix it, but just told me to check in at the airport. Seat back entertainment was great. Could be better if the audio could connect to Bluetooth.

4.0 Mediocre

James, Oct 2026

It was the hottest flight I’ve been on in a long time. The female flight attendants were not nice.

I'm 6' 2" and even in economy plenty of leg room
