It was one and half hour late... Not sure if any other experience matters.

Delayed flight. Nicest crew member was a SW pilot flying seated next to me who kindly move to seat the final passenger. Flight extra delayed. My cup of refreshment of ginger ale was so packed with ice it was literally 2 sips.

For my birthday trip this was my second time ever flying, this trip was the best.

after landing, we stay 2 hours on the taxi way before reaching the gate The airline and the crew were good though

No trays in our seats, we sat in first row, purchased a business class fare. Had to hold our drinks and snack in our hands. No plugs for our cell phones. Had to pay for it a drink cocktail each. Seats so uncomfortable.

Flight wasn’t even full, but too many carry-ons caused us to run out of bin space. New bag fee has folks who would usually check their bags carrying on. Watching Southwest morph into Spirit/Frontier is so sad to watch

Sat on tarmac for 2 hours and then missed my connecting flight

First time traveling on Southwest since bag fees were implemented. Usual good service. Just more expensive now.

Everything was on time. I was disappointed by the front section female, African American flight attendant. I did not see her name tag or would have identified by name not race. As passengers moved to the bathroom early in flight, she would say with a disdainful tone “I have to say the seat belt light is on” then go back to her book. Better trained flight attendants say something like be careful the seat belt light is on.

Cluster mess boarding. Can't wait for SWA reserved seating. Internet didn't seem to work on the plane.

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.

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

Seats were not too comfortable; it was impossible to locate the underseat power outlet.

You get what you pay for with JetBlue. Every little thing costs more, you are nickel and dimed until the end. Entertainment doesn’t function. Flight attendants do the bare minimum.

The check in and boarding process was a bit of a cluster. Two people at the counter to check in, three random lines that nobody knew which was for what, and people kept getting shuffled from one line to another for no apparent reason because then they’d get shuffled back and end up getting out further back in the line than they were originally. I only had to hand my already checked bag over and it took 45 minutes. I was never assigned a seat so when I tried to board I was pulled out of line again while someone had to try to manually assign me a seat. During the flight I got up to go to the bathroom, and there was an attendant in the aisle offering pillows etc and it was a 30 min wait unbuckled standing by the bathrooms because she said I couldn’t go past her. First and last time flying jet blue to be honest.

Communication since no reason or explanation was given for 3 hrs delay

Flight was delayed several 3 hours - no reason was given and no communication what so ever.

No overhead baggage room even though I was seated in row 2. Consequently had to check in my carry on bag. Baggage carousel was jammed. Took 45 min to get my bag.

Amazing food, great staff, with one noticable detail missing ...but no seat entertainment in any of aircraft ...I am not a fan

I wish American Airlines would change the airline industry by loading the plane back to front instead of front to back. Planes would board so much more smoothly and quickly.

I have long legs, my foot was out in the aisle and when a flight attendant came walking by and I didn't notice, instead of saying "excuse me" or anything like that, she kicked my foot. Extremely rude

Excellent! The gate agents were kind enough to rebook me on an earlier flight saving me from a 6 hour layover. Even my luggage made it despite the fact that the connection was technically too narrow. The flight itself was very comfortable, roomy, and clean. Plenty of space for my carryon items with plugs to charge my phone. After a long international flight of 14 hours, this was an excellent way to end my travels!

Great experience. Flight boarded easily. Departed early. Smooth flight. Great arrival in DC--almost no taxing! Almost direct to gate from runway. Crew was terrific. Same cookies and beverages in main cabin. I did not use the entertainment system on this flight.

Most of the delay was due to weather which is not what was at issue here. One delay was due to a missing flashlight and in the end the flashlight was actually found on the plane. The entertainment system is very limited. Live TV options offer only a few channels that are not very appealing. Boarding and deplaning are always difficult. It just takes too much time to get on and off the plane. On the plus side, I missed my connecting flight, but was easily able to book a later flight from the app while enroute.

You were more on time than United. I'm so over united delays.

The meals were mediocre and the alcohol selection was poor. I enjoyed the selection of movies and other entertainment.

I chatted with the captain before the flight, and similarly during the welcome announcement, he warned of a turbulent flight that may impact the in-flight service. However, once at altitude, he announced that the weather changed and he immediately turned off the seatbelt sign. But it appeared the cabin crew had already decided to take off this flight. They remained seated and then just chatted in the galley. The flight was fully catered, but only first class received service.

My flight attendant was attentive! The elderly person next to me was flatulent and the flight attendant could see that I was in distress and brought me some face masks
