Delta staff was exceptionally helpful and considerate. However, the first two of three flight legs were delayed making connections tentative and stressful.

Unprepared to rebook a flight of people. Uncommunicative. When I received updates in the app it was well after the announcement in the hold room. Offered a single $12 meal voucher, not enough for a sandwich at DEN, for a 17 hour delay. No one was able to explain their meal or hotel reimbursement policy for this cancellation, just handed a card to call the Help desk. My previous flight went through several delays and was finally cancelled, without explanation. The customer help desk closed while there was a long line. I then waited in line for a gate agent almost an hour while simultaneously on hold and trying to text with a remote Delta agent. Communicating with the text agent was almost impossible; they could not find any flights that got me back to my original city before the following evening. Kept offering itineraries that did not get me back to my origin airport or involved additional layovers. In 50 minutes on hold, never got through to an agent by phone. Finally spoke to one of the gate agents who was able to rebook on a red eye that had only one stop and got me back in the afternoon the next day, rather than late evening. Later by email, Delta offered 10,000 loyalty points for the inconvenience of the cancellation. The crew on the red eye flight were delightful. I don’t remember any food or entertainment on that flight.

Easy on easy off and the staff onboard were wonderful. Left on time, arrived a bit early.

No entertainment on flight, no food service, could not connect to WiFi

The plane was not clean. Vomit was removed from seat-back pocket right in front of me. The flight attendants were rude to one another. 3 children were seated together with their parents across the aisle. The children fought physically with one slamming another’s head into the plane wall at one point. The parents were aware, but took no action to intervene. Delays occurred in Atlanta after boarding before takeoff, in the air, and in Detroit after landing (no ground crew assigned). Flight attendants offered no support for connecting flights. There were weather conditions on each end of the flight, but I didn’t mark down my ratings for these.

We had a great experience with Delta. They helped us from the start at the kiosk all the way to our final destination, including help reassigning and upgrading our seats free of charge at the gates, escorts with the wheelchair for my brother and even getting our luggage at baggage claim for us. I also had special help because I forgot my pillow on the plane. The wheelchair escort contacted for associates at the check-in desk all the way back to the plane and retrieved my pillow for me.

The internet that was free was terrible, the turbulence was pretty bad - uncontrollable I know.

Very good flight. Crew was great. No issues and we even arrived early.

Got rerouted from a straight flight from Orlando to Atlanta to Knoxville to a flight from Orlando to Detroit to Knoxville! Seriously!! Flight delay out of Detroit! Long day for what should have been a pretty easy travel day!

Boarding in Amsterdam is always chaotic. More complicated than needs to be ( boarding pass checked twice, once for general security, then by the airline). The bathrooms on this flight are dirty, and smelly. The food was mediocre at best The crew was decent

It was awful everything about it terrible I will never ever ever ride it again

Frontier line changes my flight schedule with out my authorization. They never ask me and with out my concern they cut off 4 hours of my vacation they force my to leave 4 hours early from Puerto Rico.

Good- no snacks on a 4+ hour flight is painful but more painful was the lack of WiFi.

Both legs of the flight were changed. The day of the flight and length of the trip.

I guess you get what you pay for. The seats are very uncomfortable and very little space. The snacks were pricey.

They switched my flight to Spirit, Never using Kayak again,

Flight was changed (according to Frontier, by Kayak) without my notification. And all flights were delayed by at least an hour and a half. Uncomfortable plane. Bad service. Will never fly Frontier again.

There were a lot of issues at the gate in Atlanta — which caused delays in boarding and getting to our destination. The aircraft and crew were excellent.

It was fine. The flight was delayed for 3 hours. I had things scheduled in Detroit, and I let a lot of people down by not being there on time.

Flight was canceled as soon as I got to the airport
