It was good. Last flight was delayed but I always say that is in God's plan

It was good. Last flight was delayed but I always say that is in God's plan

It was just okay, no frills, basic transportation with no luxury. No screens on the seats, no water or drinks on a short flight. Full flight but at least it was on time.

Plane was clean and comfortable. Flight attendants and gate staff were professional, friendly and efficient. Boarding and deplaning were orderly and efficient. All in all, the typical excellent Southwest experience.

The seat was not comfortable. 1D. My back was sore all night and the next day.

The new boarding process was easy and straightforward. Very pleasant.

It was as expected and I was grateful for the wheel chair help and ease of use.

No food or entertainment, just a quick 40 minute flight. A little bumpy due to Santa Ana winds but pilot has no control over that. Good flight and landing!

WiFi did not work. Boarding with the new seating assignments took too long. The temperature in the terminal was obnoxious. +/- 80°

On time. Friendly staff. Took to long to pre bord all the specialty groups. Cramped small plane

The movies using Southwest WiFi kept pausing and I had to restart multiple times.

Flight staff and all was fine. Food always sucks on planes so nothing new.

We had to wait almost an hour for the wheelchair porter to be ready to pick up my mother. And when she arrived in Newark airport the porter was not there and she started walking with her cane and her poor mobility. When the Newark porter found her they didn't want to transfer her bags to the wheelchair for her.

Flight was 3 1/2 hour delayed with no credit or meal vouchers

The plane was so gross and dirty. Literally saw dust layering and flowing out the grey vents. Dust was all over the air vent knobs to the point where I took my sani wipe and cleaned them down so at least it wasn't blowing my my face. Also, I upgraded and paid for Wifi and it's always so spotty. I get we are in the air, but don't charge for it if it's not going to work. I expect so much more from United. They really are giving up.

Too many canceled flights and kept my wife and I separated on alternate flights. We did not fly out of Denver. We paid a lot of money for the seats we wanted and now that money is gone and we did not sit together. That being said, the many agents were very friendly and did everything possible to help us.

It was soooo hot I was sweating even at altitude. I know you want people to sleep, but keeping it that hot is stupid!

Your app is impossible to use. I couldn't load it. Then i couldn't open it. When i finally got both those things done -with much help -then i couldn't open the app to install a credit card. The upshot was 4 flights without access to food or drink. When i first tried to download united app some company called starlier opened instead and i would up signing up for some 49 dollar a month music service which i still have not been able to cancel.

I contacted both carriers months beforehand to change the cabin (booked in April) but to no avail (united asked to contact Swiss since it was their equipment, Swiss told me to reach out to united). So yeah… My seat was pretty worn down, legroom on 27K was more than enough, but still economy seating so, getting to know your neighbours was easy. According to ground staff, the flight was massively overbooked- and this showed. I ordered a gluten free meal beforehand (which was honoured) but for breakfast got a bread roll and croissant 🤷🏼‍♂️ The connection itself is great. Leaving SFO late PM to arrive at ZRH in the afternoon makes it easier to get re adjusted again. However, and since I’ve flown this connection a couple of times in the past, I will rather deal with one carrier only and include a layover on the east coast.

Nothing bad to say about the actual crew or airline. It was nice to have a complimentary FULL can of soda, as well as a snack. Blankets and earbuds were also provided at no cost for this red eye flight. I especially appreciated the free WiFi and movie selection with the Bluetooth option. It helped the flight pass more quickly. No matter who you fly, boarding and disembarking are always SUCH a pain. As I mentioned, this is on the passengers and not the crew!!

You can not pay credit Card for purchase Of food in airplane

Tiny seats, no entertainment, no amenities, delays, they charge for carry on and their allowed personal item is smaller than in other airlines.

Frontier.. nickel and dime add-ons. Flight late, on time, late again, last minute gate change, arrival gate required a shuttle to the terminal. They sure keep you guessing.. if you like a little chaos and airport anxiety, this is the airline for you!

baggage clamed had to wait over a hour and half for all people on my flight it was terrible

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

First of all, we never got on the connecting flight to Denver. They delayed our flight for two hours. If we would have gotten on that flight, we would have been stuck in Denver for 13 hours. So we re- routed our flight for a straight through flight to Oklahoma two days later. THEN, they delayed that flight for two hours. After that we were able to finally get on our flight and come home. Frontier Airlines - one of the worst airlines I have ever been on.

The worst flight of my life. Never will I fly frontier again

An absolutely fraudulent experience. Extremely unprofessional. Terrible in all ways possible. Rude staff, flight attendants, and deceptive "policies."

My first flight was moved 6 hours causing me to miss my meeting. The second was delayed about an hour and a half. Most of the crews apparently dont like their jobs or just working for Frontier. Only one flight attendant wasn"t snappy or rude.

First time experience and though you'll pay for *everything* meaning bags, water/snacks, even a question with a service agent - - all in all, not a bad experience whatsoever.

I like the easy check-in and boarding process. I love the non stop flight
