Friendly crew kept coming by to make sure all was ok, provide additional refreshments, etc.

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

Red eye from San Diego. Temperature of the cabin was way too warm and the air duct flowed very little air.

Overall good, just screaming kids in the area the whole flight.

My experience will Southwest was good. I wish there was more entertainment and the boarding process was slow at time but other than that my experience was great definitely will be flying with SouthWest again.

Haven’t flown on SW in years. Flight was on time departing and arriving. Served vegan butter onion flavored pretzels which were bad. Coke served was in a tiny paper cup. Crew was not engaging. Felt like they were going through the motions. Old plane, tight seats and no leg room.

No delays and arrived to destination 30 min early. Staff was super friendly.

Pretty standard flight. We left late, but arrived early. The wifi entertainment is always nice. The free snacks and beverages are simple, but appreciated. I'm tall and the seats are an issue. I can deal with a short flight, but any longer, I have to find another airline where I know beforehand I have extra legroom.

Awesome experience. No in-flight video or meal. Still do not like the boarding process.

On time, good crew, easy flight. Just like the old days!

1. Everything was satisfactory concerning the flight. 2. Can't think of what could be better right now.

Onboard staff was courteous, helpful, responsive and friendly. The boarding process was disorganized, poorly communicated, and disheveled. Gate agents were yelling instead of using the PA system, didn’t communicate the timing delay of our flight, and created an atmosphere of chaos rather than order and communication. As far as I know, there was no reason for their. I would hate to see how it operated under extreme conditions. I’ve never seen United Airlines operations in such a state.

The flight did not have its customary snacks during the flight. Apparently they were never loaded on the plane.

Worst service- attendants dont want to help and sat us in front of bathroom

We sat on the hot plane for ours with very conflicting messages. Some (most?) of this may be due to the flight control staff, but we were also repeatedly getting "we are leaving"/"we are not" messages. It was very uncomfortable

Staff could’ve been a little more cordial. The men were much more friendlier than the women. My daughter and I also missed the 2nd to last meal as we were sleeping but that is on us.

Like: departed and arrived on time. Unlike: Food options for purchase allways bad, 1 of 2 of the crew members not very friendly at all. Seats and leg room aweful. At this point I am thinking on switching to AA.

Over 5 hour delay with minimal updates or ability to standby for alternative flights. During boarding and 1 hr+ wait for takeoff, seats were drenched w water from air conditioning condensation and always leftover crumbs on carpet and seats

Our flight was canceled same day and we were never informed. Had to pay more and worse seating on another airline.

Did not like that we couldn't complete check in on-line without providing pictures of our passports. Worry about identity theft. We had no delays and boarding was handled In an efficient manner.

They cancelled our flight two times after rebooking us for a later flight. We never got on the plane. We found another solution by driving.

Mostly great. Only issue was with the WiFi. Halfway through the flight it was spotty and I was unable to work as I planned. This impacted my work products as I am traveling for business and it was an unexpected hindrance which was inconvenient. Flight here was amazing. For a 5 hour flight something more than a Biscoff would be nice but I’m just swinging at windmills I guess…

Delayed boarding because a flight attendant couldn't find the gate...sat on the plane for over an hour at the gate because AA couldn't get one of the planes behind us to move

The seats were extremely cramped, with very little legroom or personal space. There was no room left in the overhead bins for a backpack, and the space under the seat in front was so limited that I could barely fit my bag underneath. Overall, the seating arrangement felt very uncomfortable and overcrowded.

As always, most AA flights that we fly are almost ALWAYS delayed and that too multiple times. Very frustrating

The small flights with Valet Luggage has a poor service

Overall a good experience, however Wifi was not working on the flight.

THe flight was an hour late. You got us on the plan and we sat on the ground for 45 minutes with no information from the pilot whatsoever. Worst flight this year.

Going non stop to lax like I paid for. Not stopping in MCI for gas. Too long of delays

Baggage claim took too long and priority bags were not delivered first.

It was a short flight so, everything went smoothly and we got to where we needed to be safely.

Loved and was pleasantly surprised by the food!! Request Lufthansa to help transiting passengers at Munich (confusion whether to go thru passport control or not).

Flight home was delayed multiple times, did not get home until 2am

I checked a bag and there was only one agent to assist all customers with any issues.

Overall a good experience as this leg I was in Business Class. The Lounge was amazing with a view of the planes. The flight attendant spoke way to quickly when giving the information for take off and landing and it would be of no use to a first time traveler. Overall a great airline to travel on.

Super experience. Earlier than schedule departure and arrival. Baggage handling was very good

Plane left an hour late, I missed my connection and my bow case was never even loaded on the plane in VA. I deal with this type of nonsense everytime I fly air canada.

Check in agent was very helpful and polite. He helped me board the earlier flight back home instead of waiting 2 hours at the airport for the next flight

Our flight was canceled at the last minute. Someone on the flight said the exact same thing happened to her the day before. I will say they helped us book a flight on another airline so that we could still make our vacation with little delay.

The flight was delayed at the last moment quoting an absurd weather reason. This delay led to an issue with my connecting flight. I was made to run (literary) from this flight to the next one ( as they preponed departure. I was still in my DCA to YYZ flight when the boarding started for the next connecting flight. After my sprint to get the connecting flight, found that no place for my carry on. Had to sit for 3 hours with my back-pack on my lap , it was the most uncomfortable and inconvenient journey with little to no empathy shown by cabin crew in both flights. Another poor show from Air Canada!! Cant help because of lack of options !!

Flight is delayed by more than an hour without any reason, the jet blue gates kept changing every 20 mins and there is no proper communication. No ear phones provided in flight, there is a screen with entertainment but what is the use, I have earphones but the console has outdated audio connections, no usb C or bluetooth, they are living 15 years behind

A nightmare. Scheduled flight delayed 2 hours then cancelled because pilot timed out . Unable to find another pilot. Really?! Weather certainly a factor, but JetBlue seemed totally unprepared for the chaos that ensued when flight routes were cancelled. More cancelled flights, finally many of us who had been bumped from other flights were allowed to board a Boston bound plane around 3:00am, delay after delay, sat on tarmac for another half hour while pilot dealt with weight distribution issues (?), arrived in Boston 4:30. Crew were wonderful- same attendants all day and night and they were exhausted. Fortunately for me and my son that Boston was our final destination, not so lucky for many who missed connecting flights.

The flight was delayed 14 hours and communication was very poor. No one seemed to know what was happening and the gate agent was trying to help people for several flights. She was by herself trying to help 100s of people.

JetBlue worker, Blythe, was so amazing at the DCA counter. If it wasn’t for her, I’m not sure we would’ve made it through. Please thank her!

On time, friendly attendants, quick wheelchair assistance and help checking in bags. Also appreciated change in seats, more forward to make it easier for my 97 year old mother to board and exit the plane. Thank you, JetBlue!

Flight was on time and smooth. Customer service was decent

They forced me to check my hand luggage at the gate.

Still hasn’t left. Why are you asking how it was?

My flight got delayed and eventually canceled, then rescheduled. I and several others had a connection from Boston to Paris and asked several times if we would make it. They assured us we would and then rebooked us mid flight without our consent and closed doors early even though they said they communicated we were a bit delayed. We got stranded in Boston and I opted with being rebooked for a different connection to France since they refused to pay for a Hotel. I've now been in Europe for 5 days and still haven't recieved my bags. There was absolutely no urgency for the fact that I'm in a foreign country with absolutely no change of clothes or any of my medication. Such an overwhelming and frustrating experience.

One hour delayed departure resulted in problems with planned ground transportation at my destination.
