Flight was delayed over 3 hours. Planes were dirty. Staff indifferent. And they serve vegan pretzels as snacks.

Flight was delayed over 3 hours. Planes were dirty. Staff indifferent. And they serve vegan pretzels as snacks.

The flight was smooth. The Southwest experience has degraded overall, but this one was okay.

The checking experience in Orlando was terrible, almost missed the flight. Too many travelers and Southwest completely understaffed.

no service at all due to turbulence. they should've at least given us snacks, there were only 10 people on the entire flight.

For the first time in a long time, the Wi-Fi actually worked the entire flight! The flight crew was amazing as usual.

We got exit row seats both flights. Everything was running on time

Flight was ok. Boarding wasn’t fun. Flights were delayed by 12 minutes on each leg.

Wifi didn’t work, no service, seats are hard as rocks

I always know what to expect with Southwest - friendly crew, on time departure, app that works great! I appreciate having free baggage, and the in-flight entertainment passes the time.

They could have served us 🍺 drinks, said there was turbulence, I must have been on a different plain flight felt pretty smooth to me. ✈️

A refund because I never got on any you guys never canceled it in the first place

No negatives. Crew was great, flight was on time and there were no crazy passengers. 🤩

No headphones provided. No gf food. Only 1 beverage cart run sAN to HNL. Rarely saw crew members

Everything was excellent. It always is with Alaska Airlines. Thank you. 😊

Flight was on time. Crew was helping & seat were comfortable.

The flight was good, but your car partner, Wisecars, was worse thane awful. They didn't have an agent nor had they inform me which car rental they were supposed to have issued a voucher.

My flight was delayed. But it was during holidays so you kind of expect things like that to happen. I am not a frequently flyer so I am OK with that. But none the less, once the flight started, it seemed to me like it went fast. 😊

I appreciated that the two flights were on-time, smooth, and stress free.

Cheerful crew, arrived early, but did have to wait for a gate because of that. But it was a pleasant flight.

No leg room but flight is smooth flying. Pretzels really?

Sat in the tarmac at O’Hare for 65 minutes. This is a regular occurrence for delta at O’Hare

Delta was fine though my flight was delayed 4 hours into LGA and my return into ORD involved a taxi of 1+ hour to the gate

It was as good as it could be. Flying is not a pleasant experience these days.

There was an unruly family behind us that made the short flight miserable!!! The cabin crew did nothing to contain it.

Flight delay was frustrating, also you cannot checkin online without delta app, web browser check-in throw errors

Got on the plane and sat there for an hour before departure.

Very large passenger too space from my own seat. Arm board couldn’t be lowered because of his size. It wads very uncomfortable trip, as the flight was full couldn’t move anywhere having back pain because of the position in which I was the entire flight.

Cramped seating for me. Luckily it wasn’t a long flight

5 hour delay. They blamed the weather but it was the computer issues they had been dealing with for days.

I usually have a positive experience with Delta. Complimentary upgrades are always nice!

The flight out of Fresno boarded 1.5 hour past scheduled and made me miss my connecting flight from SFO to SEA.

Crew was great (professional, attentive, prompt). Snacks for 4 hrs flight is deplorable.

Flight delayed. WiFi connectivity very poor if not existant. Last minute arrival forced me to run to catch my connection.

It was a pretty standard flight... until the almost hour and a half spent on the taxi way. I get that the weather has been poor but the delay had nothing to do with the weather and more to do with a plane with several issues tying up the gate. I get that that happens from time to time but this has been EVERY flight I've been on for the past 5 years and I fly 3 to 5 times a year. This isn't just United... it's American, it's Delta. It's an issue with the entire industry. I work for UPS and packages on a cargo plane get better service than people do these days. Anymore I HATE flying.

While the staff was pleasant and helpful, the following observations are for your awareness. There was some delay on the tarmac on take off and landing. The paid lunch/food offerings were limited. Entertainment was only available on WiFi at a cost.

The first flight was better in terms of the aircraft.

As usual, United scheduling is completely misleading. A 54-minute layover at O’Hare is too short to make a lot of connections, especially since the flight landed “on time” but had to wait on the taxiway 15 minutes for a gate to open up. Then it takes another 10 minutes to exit the plane before one can run to another concourse to catch a connecting flight.

when you can say you don't remember being at any point upset during a flight, the airline is winning .

I had a great flight. Everything went smoothly and the flight arrived early.

It was fine. Everything ran on time, crew was great.

My seat had a worn out cushion, which made it a bit uncomfortable. Other than that, the flight was excellent.

The flight from LA to Chicago was smooth and service was very good overall.

The chicken wrap was tiny ($13 for what looked like a 1/3 of a normal wrap?) and disgusting.

We flew in first class. The crew did not offer drinks before the flight took off, but they treated us well during the flight. The food was excellent. There was actually too much food served, but it was nice to have all the options.

Was not able to watch most shows on the entertainment site. They would not load

The plane was late and then sat on the runway for almost 45 minutes before taking off.

Had to wait on pilot and crew to depart and had to wait to arrive at the gate because they only had 2 crews working. Delays, delays....Planes just keep getting smaller and tighter and they nickle and dime for everything. When will an airline actually wake up and make flying more enjoyable?

It was nice being on a flight that had working wifi. The boarding was quick - why don’t all airlines have small boarding groups window to aisle? Makes so much sense!!! I was disappointed to be the first person stopped to have to gate check my carryon. Especially when there was plenty of overhead space at the back! But I get it…keeps it moving. Crew was nice.

The flight encountered a delay exceeding 4 hours. The food voucher issued was valued at $12, insufficient to cover our meal expenses. Consequently, I was unable to take my medication, leading to a drop in blood sugar levels and exacerbating my anxiety.

We experienced an involuntary change of schedule. Had 1st class tickets from Fresno to Bonaire, put us in coach from Miami to Bonaire a few days later - terrible flight, try to get a refreshment , water or a meal and air. We will never be subject to that again. I'd rather fly another airline that honors 1st class. Adding insult to injury AA reimbursed my wife's ticket $106.66 for the change in seating, me nothing. Haven't heard back from Customer Service, don't expect to - it's only online, can't speak with a live person. So the difference between 1st class and coach for that portion of the flight is only $106.66? Really? I've flown Delta and United on the same route, will go back to one of them again.
