My flight from Atlanta to Oklahoma City was delayed multiple times. I ended up arriving in Oklahoma City nearly two hours later at around 1:50 am the following morning. This was a highly disappointing experience.

Love Delta. I'll take connections to stay on Delta even if another airline has a direct flight.

This flight was the flight we missed due to deltas delay at our first airport going TO Atlanta.

I enjoyed the whole flight and the crew was amazing i dont usually fly delta

Flight attendent didn't let me sit in the empty window seat literally next to me. Doors had closed already so I moved over. She came over, asked for my ticket and made me switch back to the middle. The man on the aisle and I were right on top of each other. Seemed like a real power trip for no reason at all.

Everything was great, from the flight and crew to the seating and snacks.

After boarding the plane had to wait an hour at the for the copilot to show up before we could depart

There was overbooking that delayed boarding. Then an airport emergency lockdown that caused further delays in boarding. However the time was made up during flight and there was a minimal delay in landing. Everything else was excellent.

It was the hottest flight I’ve been on in a long time. The female flight attendants were not nice.

The flight was freezing cold. I had on pants and a sweatshirt, had to wrap up in the blanket provided AND put on my rain coat, and was still chilly. Have never been on such a cold plane.

The boarding agent and checked bag agent were both rude. It only takes a second to be kind. However, the flight crew was amazing. I got a turkey sandwich and it wasn't bad---not great but not bad. The internet was my biggest problem. This was a work trip and I REALLY needed the internet to meet a deadline but it didn't work for 80% of the trip. Very disappointing.

I tried to check in beforehand from Ireland. The Jet Blue website sent me to the Aer Lingus website and vice versa. I tried to get a boarding pass at Dublin Airport as well, but they said they couldn't help me either. I had to wait until I arrived at the gate in Boston to secure a boarding pass...it was a bit nerve wracking.

Great flight. Best in years. Very clean craft. Easy boarding. Communicative pilot. Friendly flight attendants. Absolutely smooth take off, in flight and landing. Very comfortable seats. Smoothest flight I've experienced in years. THANK YOU JET BLUE!

I was asked to pony up an additional $239 (over the $735 paid originally) for a one way middle seat, which was very uncomfortable. Where did you expect me to sit?

Jet Blue sevice was good. Just don't understand why they charge for earphones to listen to flight entertainment. Other than that, everything was excellent.

Mostly good, flight take off in time and land earlier I can’t ask for more..

The crew was not nice this time. I asked for a drink one time and the girl didn’t say anything to me and just got me the hot drink while walking super fast to the back. We were sitting in the back and she wasn’t doing anything except socializing. She was upset I asked for something and she had to do her job. I also didn’t fully have it in my hands when she handed it to me so it was dangerous. She was abrupt and rude. She wouldn’t allow for people to spread out like previous flights we had been on if they were empty, and there were empty rows. It was strange and she enjoyed being angry at us.

It was my first time in Jetblue flight in 10+ years(?) and the experience was horrible. You were better before. There were ATC delays sitting/waiting in the tarmac for 2 hours, I understand that this isn't Jetblue's problem but how the matter was handled poorly is. Cabin was so warm and hot couldn't get it to cool down for the entire waiting period worse, even during cruise flight. Start, the passengers were spoken to and treated like a little children with no respect. Constant/multiple annoying tone/voice PA announcements of mentioning "... only big/large suitcases are for the bin and small ones need to be placed under the seat, etc,..." I see that flight was delayed and crew were trying to get the plane ready to board as soon as they can but the way they presented was lack of better word, condesending and scolding tone to cattle. It was definite unpleasant, unwelcoming flight experience I have ever had with Jetblue. Whatever happen to smiles and fun employees , pleasant/helpful gate agents, flight attendants, crews, where have they gone? It was dissapointing flight experience overall from everyone. Sorry for the direct transparency.

Separated a pair of family members(father and teenage daughter) on all legs of the flight that were booked together, just to create an upsell. Food was horrible and only catered to vegetarians and gluten free crowd. I’d rather give more of my money to another straight shooting airline.

Not very happy because of the long delaying which causes our luggages were not on the connection flight and nearly missed our connection flight.

At 5:46 am EST, when I arrived at my departing gate, your gqte agent told me that I could not board the flight because the flight is closed 15 minuets before departure. However, the same gate agent escorted a woman (standing right next to me) at the gate onto the flight which, proves that I could have boarded the flight just like the woman I watched board the flight. The gate agent stated "she was here before you". 1-why was she not already on the flight & 2-how and why was she able to board a "closed" flight that I was not. Additionally, although 6am EST was the time of departure, the plane did not 'pullback' from the gate until 6:15am EST The same gate agent told me that the "boarding closes 15 before departure time" is printed on my boarding pass. This statement is not displayed on my digital boarding pass that I downloaded from AA.com. She also told me that this in stated on AA.com whent I booked my ticket however, since am travelling for work, I booked my flight thru my firm's (Deloitte Consulting) corporate travel app, not AA.com.

My flight depature was changed. Then it was delayed, and then cancelled after I reached the gate.I paid $231 for a hotel room that I didn't get to use because I arrived 24 hours later than I was suppossed to. My wife had to pick me up from the airport and I had to pay for an another ride back to the airport the next day. They did get me faster/ priority through TSA. The 2nd flight was okay

It was a short flight so there were no entertainments nor super comfortable which is OKAY, just the review system doesnt allow for N/A which is why okay was put, but overall good! No delays and nice crew

It was significantly delayed. Also the admirals club in Philadelphia airport near Gate B is absolutely filthy. Good was on the floor. Flies on the cheese. And the men’s restroom had pools of urine on the floor. I am not using that lounge again.

It was good overall. On my transition from Philadelphia to Boston,the gate information wasn't correct. When I went to check the gate information; I found out that my flight was boarding clear across the airport at another gate. Fortunately I rushed over there and made it on time while they were in the middle of boarding.

With weather and severe delays it was disappointing we didn't receive any compensation for the 5 hour delay. Not even a food voucher.

ATL to CLT return flight. Delayed way too severely. Had to cancel the return flight.

Uncomfortable seats, spotty WiFi, only Biscoff for snack (no one likes those).

Booked flight at 8pm Sunday evening. Flight posted delay from 5:00 to 7:46AM Monday morning. At 12:26 AM (after I was asleep) pulled flight forward to 6:21AM. Had to scramble in morning to make the flight. Barely did

American Airlines flights are always delayed for some reason. It took 9 hours today from Atlanta to Austin. I will go back to Delta.
