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°

Paid for premium extra leg room but the bin space for rows 1-3 had to go in rows 4-6 and 4-6 had to go to 7-9 because flight attendants have snacks and their luggage upfront. So we pay extra to have to fight thru traffic to get our bags. Only 2nd day of new seating so hope they fix this.

The seats were a bit cramped and worn, but otherwise okay.

Since the flight wasn’t full, we had some extra room. Crew was great

Delta is always a wonderful experience. A clean plane and the crew is really friendly.

Air travel sucks. It continues to be awful for all airlines. No shame on delta alone.

Lady Pilot was perfect in every way wheels up to wheels down communication, professionalism, excellent on time departure and on time arrival, excellent communication! Fantastic job with Superb attitude!!

Everything went well and was good. Nothing exceptional, but no complaints either. Cheap seats are pretty comfortable.

De planning was an absolute mess. We were never told that we weren’t at the gate and that we had to go down unstable stairs and then hop on a bus. People were falling, we couldn’t tell who was in charge. Overall terrible communication that ended up leaving a bad impression at the very end of the experience.

Long line to check bags. Curbside check-in was closed. Seat back monitor was not working.

Left on time. Arrived on time. That’s all i ask.

AC barely worked on a 50 minute flight. It was very warm the whole flight. Flight was very bumpy and hard landing.

Everything was very good other than I had selected a specific seat when I booked the flight and they changed it once I checked-in the day before my flight. I was still in first class but lost my aisle seat for a window seat. Being tall, the aisle offers more comfort so I always select an aisle seat.

My flight was very clean and the location was comfortable. The service was great. A satisfying flight!

Short flight, but no drink/snack service. The flights both going and coming were delayed.

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

weather delay of almost 2 hours then we landed and our gate wasn't available so we waited another 30 min

We got delayed getting out of DFW for broken overhead bins. Once the flight got underway the captain kept the seatbelt sign lit the entire flight despite little perceptible turbulence, preventing use of the rest rooms and any sort of refreshment service in the main cabin.

The gate got changed several times and the flight was delayed over an hour. Awful experience

It was an older plane. First Class was not especially roomy or comfortable. It was a short flight so there were no meal but they did offer mixed nuts which used to be normal but now is rare. Crew member was very polite and professional.

It's very confusing because Kayak has it as American Airlines, but it was Hawaiian Airlines, but operated by Alaska Airlines. I had to go to the airport for my boarding pass because American said I didn't have any trips.

No Snacks or Entertainment. The flight was short, snacks should still be given.

The boarding was pretty easy. However, the first class seats are not lay flat as other airlines (like JetBlue) has and therefore sleeping was a challenge.

Everything was fine. Flight boarded and departed on time. Seating was spacious enough for my carryon to fit under the seat in front of me. No complaints at all. Flight even arrived early.

Boston ticket agent Cheryl Porter is WONDERFUL. Our Iberia flight to Barcelona was cancelled the morning we were scheduled to leave and Cheryl was our super hero - she found us seats on a flight to London and on to Barcelona. Truly a “can-do” attitude which we appreciated so much after the Iberia ticket agents told us there was “absolutely nothing they could do”. (As did the customer service agents at Iberia’s call center) Ms Porter is truly a wonderful person who genuinely cares about travelers!

Nothing wrong on this flight but nothing special. It was oversold and they had to bump people which is always bad.
