Anonymous, Mar 2026

No pilots so we were two hours late taking off and then no gate agents when we arrived in Salt Lake.

2.0 Poor

Susan, Mar 2026

We landed and sat on the tarmac for 45 minutes because they only have one gate at the airport and there was another plane running late so we had to wait

8.0 Very good

Douglas, Mar 2026

The WiFi was not working. That made for a long flight.

10.0 Wonderful

J, Mar 2026

With Aeromexico it ended up good but with Delta it was bad because we did everything through Delta... Showed up at the Delta terminal... It was the wrong place! Nothing ever told us to go to the Aeromexico terminal. It said "in partnership with Aeromexico" but I was never instructed to check in with them or go to their terminal. We had to haul @$$ running through the airport and almost didn't make it thanks to this poor communication. 👎🏽

4.0 Mediocre

Jeffrey, Mar 2026

Absolutely no communication on why there's a delay and multiple flight time reschedules. I would have canceled the flight and drove back home if I known it was going to be rescheduled 3 or 4 times.

8.0 Very good

Stephen, Mar 2026

Good food and people

Isabella, Mar 2026

Another late night flight and MORE men belligerently drinking and yelling. I had to move from first to economy because they were so obnoxious and disruptive. Crazy to go from a cozy chair to cardboard when you were supposed to be in first. Delta allows was too much drinking which leads to belligerent behavior.
