Having to up charge for a seat assignment is not good. Delta can do better

Having to up charge for a seat assignment is not good. Delta can do better

I liked the friendliness of the staff. The cleanliness of all 3 planes.

Was charged for my luggage despite having been on one ticket from an international flight. Too tired to argue after 15 hours on flight. Was charged for rechecking it at JFK airport. Not sure why those off Kenya Airways were required to do that.

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.

My experience on any Delta flight is always overshadowed by the time Delta removed me from a flight for no apparent reason.

Delayed and took off even later than the scheduled delay time

For a 69 year old with health problems I had the worse experience, no wheelchair when I entered a lady told me to sit and wait while a gentleman told me I had to walk to the Delta station, which I did. I had a carry on and a bag, and I was traveling with my service dog, which was on his carrier and the lady charged me for my carry on luggage, beside all the waiting cause of the delay, I had to walk to get my luggage cause no wheelchair showed up, I am so disappointed. I will get in touch with the company. I got home at 3:00 am, not good for my health situation.

Only issue was with seating. The economy fare we purchased did say there was no guarantee the three people in our party would be seated together, and we were not. At the gate, the agent told us more specifically, the fare we purchased meant we would be seated in middle seats only. This should just be made more obvious.

Great experience on Delta. Staff from baggage check to flight attendants were very courteous and professional. My only issue was a personal preference for pretzels instead of the chips and cookies that were offered.

There was no problems, just a little uncomfortable with seats that do not lay back a little

Excellent flight. Boarding was efficient and departure was on time. Smooth flight with on time arrival. Deplaning was also efficient.

This flight was perfect. No complaints and only the highest regard for the crew and ground staff and how they executed perfectly. I fly a lot with United and would request predictability and transparency in their operations instead of last minute changes.

This is for UA2274 from Houston to Sacramento. The flight was delayed arriving due to mechanical issues so we left about 3 hours later than scheduled. When boarding the plane the temperature inside was excessive - likely close to 100. Pilot apologized and said it was going to improve at altitude, which it did. But before that I honestly thought there might have been more delays removing passengers made ill from the heat. We were delayed leaving due to another mechanical issue. There was not water on the plane due to a panel that was not secured. They did that quickly, but the combination of mechanical issues was rather disturbing and did not reflect well on United.

1. when we went to check in, our 2 first class seats had been CANCELED and the flight was sold out. This was done without our prior knowledge. It was all we could do to restore one first class seat for my wife and I flew economy. 2, Our flight home was scheduled to leave at 10:30 pm. Due to tsunami warnings, the roads were closed and our flight status was uncertain as to whether it would leave as scheduled. It was announced that it would now leave at 11:20 pm and the roads were now open since the tsunami had come and gone. We made a mad dash to the airport and checked in. Delays were announced at 12:30 pm, 1:30 am, 2:30 am and at 3:30 am it was canceled. Since this was a flight due to natural (tsunami) causes, there was no compensation. We were told to return at 1:00 pm the next day and our baggage would be kept on the plane since the same plane was going to leave at 1:00 pm. We had to return to our hotel for the rest of the night. The same plane did not leave at 1:00 pm and our baggage was gone! All in all, it was a miserable performance by UA. Information was hard to obtain and no one knew what was going on and what was going to happen. Hundreds of passengers slept on the floor, chairs, etc. No food and no water was made available to the passengers. It was a situation where UA could care less what was going on. As a one million mile flyer, I had not experienced anything like this before and it was hugely disappointing!

Staff members were not helpful they ignored all calls for an attendant.

Flight was delayed and missed my connection Lufthansa didn’t respond.

Terrible. Delayed 7 hours, and cancelled the flight, leaving me stranded and out of pocket $500 for an alternative last minute flight

Was on time until within 1 hour of flight-how does that happen? Staff very friendly.

the delay for 3 hours was understandable due to weather conditions but the flight should’ve provided some on flight compensations or at least provide more food.

Weather delay in Chicago?. No sense of urgency to make connection in Chicago for our connecting flight that wasn't delayed. Connection was missed.

Flight was delayed. Staff at the gate effectively and proactively communicated about the delay.

The plane was broken so we had to change planes.

Overall fine, but the delay was annoying and the reasons for the delay were not communicated. The crew on board were phenomenal!

This flight never occurred because AA couldn’t get their act together.

Boarding was very efficient. Everyone got on board and we got on our way very quickly. It was frustrating that the entertainment app was not functioning properly. I was not able to activate some of the movies offered. The crew on this flight appears to be pretty grumpy. They had no smile on their faces. I felt like they were doing us a favor for being there.

Delayed because of weather in Nashville. I think God or some higher power generally has cursed me when it comes to flying out of Charlotte on American. I'm delayed pretty much everytime. We need Team Cobra Kai types to come in and "sweep the leg(s)" of the Charlotte ops people on principle. Don't let the sweet southern rocking chairs fool you, Charlotte is a sinkhole

Long 5 hour and 45 min flight and only one drink service and cookie snack

Newark airport grounded inbound flight and only announced when the flight was about to start taxing.

Was a normal flight but it was delayed, and there wasn't an explanation.

Terrible. The flight was delayed two hours due to weather. Then when we got on the plane, the first pilot ended up timing out and we had to wait for a second pilot. Second pile came on board and we tax it out. Had to return back to the gate because of an unruly passenger. Then the copilot timed out. Had to wait for new copilot. Also had to wait for maintenance to check for fuel. Then found out the second pilot timed out and we had to wait for a third pilot. Was ready to go and then needed maintenance again for another issue. In the end, it was 2 o’clock in the morning when they announced that the flight couldn’t go because the third pilot and the second copilot had timed out.

Worst flight experience ever flights canceled. JetBlue told us just did not even bother standing in line to come back in one and a half hours then without any information we had to go pick up all of our luggage and spend over $2000 in accommodation just to get home. JetBlue said that the next flight available for us to get home would be three days later. Absolutely absurd hasn’t offered to give us any compensation do not fly JetBlue horrible company. They said it was based on the weather and the weather is great in all locations that we would’ve been flying to total hoax. I think it’s a conspiracy theory.

The captain gave good announcements and the flight attendants were friendly. The WiFi was pretty good. The plane itself looked very old inside and the seats were very uncomfortable. The screens in the seat backs were the smallest I’ve ever seen. There were so many loud and obnoxious kids on this flight and the parents didn’t do much to try to quiet them down. Some had videos and games on tablets with higher than necessary volume going the whole time.

Too many long delays with JetBlue. Worst major airline that serves JFK but unfortunately I keep going back because of the prices.

My JetBlue experience was nice. The flights ran on time, the aircraft was clean and comfortable, and the flight attendants were attentive. My only issue, which is isolated to the low-cost (budget) option at JetBlue, is that the check in process makes the user feel that they have to buy their seats. The seats offered for purchase are upgrades from the budget seats you get (which are essentially the last seats remaining). The interface should not make it feel like you must purchase a seat.

The plane was late to leave.. Internet was lousy. TV was not working. when we arrived, We stayed on the plane for a long time before we got to the gate. It took us a long time to retrieve our luggage because they didn’t know what carousel to send them to. It was a bad experience.

I especially liked the lead crew officer. His boarding and safety announcements were made with a bit of novelty and humor. The flight also left the gate 10 minutes early and we landed about 20 minutes early… It was a delightful flight…

There were mutliple delays. There was inconsistent, delayed, and poor communication regarding the delays.

flight was delayed for hours with no explanation. The plane was a very old aircraft.

Spend hours delayed with no food, water anything sitting on the aieplane with no ability to eat or use the restroom. My entire experience was the absolute worst. I will never fly jet Blue again.

It would have been nice if they had offered more than one set of snacks
