Missoula is a great airport. Desk and gate crews were very helpful and friendly

The flight was delayed out of BIL so many times that I was not able to make my connection. I was rebooked for the next day, losing a full day of my trip. I still have not been compensated as promised.

2 hour delay. Then some luggage was unloaded at 1baggage claim #7 then without notice the baggage claim was changed to #12. No one informed the passengers they were changing baggage claim turnstile. Several of us waited for 90 minutes after the 1st turnstile stopped and changed to other flights luggage.

The seats are too small/crowded. It is frustrating to be forced to sit with someone who is overweight as they crown the other seat. Nothing against the person…just the airline companies who continue(over decades!)to reduce seat sizes. Americans are fat. Those of us who are not are tired of being compromised by the airline companies who don’t faces that fact and make adjustments. Maybe have “overweight seats”? Maybe give us a discount for being forced into an uncomfortable flight due to others overweightness? Please, make adjustments…be accountable. Thanks!

The crew was great and everything went smoothly coming and going.

No outlets, plugs, way to charge the phone or service and no food on one leg o the trip, but other than that, great. Loved WIFI, the flight, the crew, the pilots, the schedule, etc. Great job. My new favorite airline!

They changed the flight time from 4:00 to 1:50. We missed the flight because we did not know. We were not entitled to any sort of refund.

Easy check-in. Good customer service. Had to check carry-on due to lack of overhead space. Wish the airplane was configured with more overhead area so this doesn't usually happen.

Wonderful as always! Pleasant staff, smooth ride, and timely departure.

No communication with delayed and canceled flights. Completely in the dark for the whole experience.

We sat on the runway for over an hour before departure. That was unwelcome.

Horrible. Faucet in sink not working, wifi not working. Didn’t bring food or snacks

Flight was delayed before take off and at landing. Baggage took 20 minutes. Flight crew would not serve full soft drink and had to ask multiple times before receiving water.

From checking to boarding, it was a seamless experience. The service agents were so helpful. The flight crew was so pleasant.

Gate agent showed up 20 minutes before boarding and was not at all friendly. Had to take this flight due to the one on the day before being cancelled and any later options were already full with long standby lists. Despite having paid for Delta Comfort seats, Delta did not allow me (or anyone) to choose their seat. The agent assigned them for everyone just prior to boarding. Self seat selection was allowed on the original flight. Flight staff was great - very friendly.

Flight attendants were great. Cheerful, upbeat and friendly. Jet, in particular, was fantastic.

I have Precheck. Flew HPN to DEN and return this past weekend. Delta didn't attach my Precheck number to this trip. So it was waiting in general line especially in Denver. Unavailable.

Original flight was delayed, then cancelled and the gate staff did not expedite rebooking. Also, no instructions were given that a ticket number was needed before being called to facilitate rebooking. This could have been much more organized.

Be on time? When not on time a circling for over an hour offer more than 1 bag of chips to the passengers? It was a 7 hour flight by the time we got done.

Five hour delays every hour, I wish it were all at once
