delta wifi wouldn’t work boarding was not in sequence flight crew spent most of their time on the phone with the lights off pretending no one wanted or needed anything

Flight was 2 hr. delay, making me miss my connection to my final flight home to Roanoke. Now 12:38am in the morning and I just got the first available ticket at 5:30 pm tomorrow evening. Sleeping in the airport.

I am a die hard Delta flyer, but they missed it on this flight. It was on their very dated 717-200 aircraft, which I knew when I booked it so I knew it wouldn’t have seatback screens. However, the internet was awful and it wouldn’t even send texts a lot of the time, much less even connect to the delta app. It was also very hot while in the air, which never happens. What was even more disappointing is that the crew only gave me cheezits and a beverage, even though I was in Delta Comfort. The main cabin fare gets these items. I didn’t get any kind of improved snacks and that was unacceptable. The crew wasn’t very visible at all either. If this was my first delta flight, it would be my last. I am just going to assume it was a one-off flight.

flight was delayed 4+ hours. there was really no understanding of why? weather? the last hour of delay was post boarding. pilot seat was broken. was that the real reason? nonetheless, long day of inconveniences.

Flight got canceled 4 times, missed my connecting flight due to delays, have to wait to go home tomorrow

We departed and landed early which was a nice surprise. The boarding process was slow.

Arlene was a great flight attendant. I also liked how one of the other flight attendants gave us a heads up about snacks and asked everyone to remove their headphones when it was their turn to order. Good idea.

bulkhead seat had very little legroom - even in bsiness class.

I didn't take this flight. I changed the flight. Why am I getting surveys and notifications on flights that I change. Seems like a defect with Kayak.

I loved having a most black flight crew during Black History Month; rather by design or accident I appreciated the representation. ❤️

Horrible. No AC. No Air inside the plane. We had to deplane twice! It is late almost 5 hrs in total. I almost passed out and about to call 911. I asked the crew to be honest and open the door. The lady next to me was lay down in the floor due to heat and no air inside the plane. I got headaches, can’t wait the replacement flight about midnight Dallas time. I end it up rebook for next day flight and stay overnight using my own pocket in a hotel nearby due to headaches and can’t breath. I still have a headache this morning. Still not decided yes how to file this issue to AA and/or FAA.

The flight was ok, i understand Houston-Dallas is a short distance. The plane is really small: no TV, no snacks, but other than that, all was good. We had a bid delay but luckily it did not affect my connection

Forced to check bags. Crew uninterested in collecting trash. Unclean seats.

There's nothing I liked about it. For first off I scheduled this trip two weeks in advance then they delayed my flight which messed up my whole trip. So I scheduled it for the following weekend thinking there won't be a delay and guess what as soon as I got to the airport we said in the airplane on the tarmac for an hour and a half. Not only was it delayed I missed my connecting flight meaning I had to stay the night at Dallas-Fort Worth airport sleeping on the floor. I will tell you this I will never fly American airlines ever again I have had nothing but horrible experience with them and I just throw money at them

They changed my seat from one that I had paid for as an upgrade to a regular seat at the last minute.

Very aggressive and unhelpful ground crew. Wanted to check my hand luggage for 3 flights. I had lots of delicate items and computer equipment. So the silly lady wanted to rebook 3 international flights because of a carry on. What nonsense. The baggage handler suggested I put it under my seat - so I did. And this was during the rebooking chaos of the Microsoft crash. She was the most arrogant annoying and aggressive ground staff member I’ve met in 20yrs. (AA flight out of Houston).

Left from gate 30 minutes before flight. Never been late to a flight ever. It says 15 minutes before explicitly on the ticket.

Was as expected. Good leg room on planes - much appreciated.

I know that there is nothing than can be done about rude customers. I did find a couple of them were very rude and inconsiderate In my case the guy who was sitting in the same row as I was in, was trying to watch a movie with no headphones, a crew member did ask him to turn it down or off (thumbs up for that.) Another thing, as we were about to land another young man must have taken his phone off airplane mode was talking with his friends and using fowl language which I found inappropriate to the ppl who were sitting in the same row as him and other ppl around him. I understand how no one wanted to address this person and not get involved. We all just wanted to get home safely with out any incident.

The food service was limited and not good. For a seven hour flight they could do better.

Plane was delayed multiple times. I would like to request a refund. Was due to arrive Thursday evening ended up arriving Friday morning.

The seats were roomier than other airplanes I’ve been on.

The crew and the pilots. The pilots were amazing. The landing in Cancun was excellent.

The security line at JFK was one of the longest I’ve ever experienced - probably 45 minutes. I don’t know if JetBlue has control over it, but it detracted from the overall experience. Entertainment had good options, but the volume control was a bit small to tap on and the screen had a fair amount of interference blips. Clearer picture would have been better.

I liked the entertainment on JetBlue, the service from JFK to JAX was terrible at best

I usually dont fly JeTBlue and I dont think I will ever do it again. The flight was delayed fee time, nobody was giving us any info at at the airport, gate changing, the slowest and poorly organized boarding ever, rude staff.. huh

The flight was delayed. I upgraded to more room. I can't imagine how small the regular seats are I haven't upgraded for my return flight yet.

see my previous response about being kicked off the flight and having to fly the next day, ruining a planned vacation tour.

Horrible - for the first time in my life i was denied boarding an international flight because the name used on my ticket - Josh - was not exactly the same as my passport - Joshua. At no time during ticketing, online check-in, or at the airport flying from Boston to NY was i notified of a problem. It was only at boarding from NY to Costa Rica I was informed of the problem and by then it was too late. After missing the flight I was told by airport Jet Blue staff, including a supervisor, that it was my problem and they could not assist because i bought "the cheapest fare". i was hung up on twice by JetBlue customer service, including once by a supervisor. I blame Kayak and your awful partner ChatDeal for even allowing me to purchase an international ticket without verifying this - you effectively sold me a ticket i could not use. Shame on you and shame on ChatDeal for doing nothing to help me resolve the situation. What a scam.

Jet blue just had great service overall! Only a little turbulence heading out of Austin, otherwise the jet stream helped the speed of the trip!
