I think in the future I cannot fly anything less than Comfort plus. The seats vary depending on the plane. The people are extremely nice and funny. I try to only fly Delta if I can help it.

2.0 Poor

KEVIN, Oct 2026

delayed take-off, then had to circle in air for awhile, wi-fi did not work, then the cabin got extremely hot multiple times and the luggage was at wrong carousel at LGA. In addition, plenty of overhead space so they checked bags too early. Horrible flight.

4.0 Mediocre

Naqhiuddin, Oct 2026

Flight was fine, it was on-time and was not cancelled which is very good. However the small cabin bag was forced check-in although once I entered into the flight there was lot of space which would have accomodated 10 such bags. Moreover this caused delay on arrival of my bag due to which I missed my booked cab and had to wait for another 20 minutes before the next taxi (Uber) arrived.

Benjamin, Oct 2026

WiFi only works on about 75% of my Delta flights. I rarely fly SW, but their WiFi works 100% of the time and is easy to connect. On my DL flight from DCA to BNA today, I try to connect to WiFi for about 30 minutes, but I gave up. I have a lot of work to do, and I lost two hours today. Very frustrating.
