Delta was great because the flight was almost 5 hours so I had access to tons of movies news, etc. so it helped past the time by no other plane WestJet did not have movies so Delta was the best

4.0 Mediocre

Jim, Aug 2026

Noting this only because it’s so unusual for delta: this was just an uncomfortable flight. The jet ridge was too hot and the plane wasn’t any better. By the time we got off the ground the AC was on but for such a short flight it was almost too late.

4.0 Mediocre

Visharad, Aug 2026

1) It was extremely hot in the cabin. All the passengers were sweating and it almost became suffocating 2) It was a 50 min flight but there was no service. How can a 50 minute flight not have any drink/snack service?

2.0 Poor

Vishruth, Aug 2026

Very bad multiple confusion and miscommunication which i ended up missing my flight.

Rohit, Aug 2026

Fine. Plane was late arriving and taking off

8.0 Very good

Stacy, Aug 2026

There was no food, so :( to that one. The flight was delayed by 3 hours. Not Delta's fault. Not the crew's fault. Considering how tired all us passengers were, everything went surprisingly well. The flight crew were very helpful, friendly, and professional. I always fly Delta.
