The seats were comfortable, and the boarding process was pretty smooth.

3 hour delay. Had to change plans and was still delayed.

The staff was very friendly, professional, and courteous. The overall flight was a great experience.

The crew canceled the complementary snack and drink in anticipation of turbulence that never materialized. I was counting on the drink (water) to take the the doses of medication - prescribed for my heart condition - that were due during the flight. Since no snack or meal was served on this flight, I cannot rate the food quality. Otherwise, this flight was excellent.

Departure was delayed more than 1/2 hour while we waited for luggage (only) transfer from another flight/plane. Once approved for takeoff, the flight was excellent.

We got exit row seats both flights. Everything was running on time

The flight crew was extremely rude and especially not helpful when our flight was delayed.

Pretty seamless, just a tad bit late in taking off and landing.

Flight was fine other than there was a gate change that I was not notified of. By chance I happened to check my phone and saw the change, otherwise, we would have missed our connecting flight.

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.

The entertainment screens were not working and there was no air condition the entire flight. Very uncomfortable.

It was Delta, but the flight attendants were stressful and disrespectful. I am a diamond member a travel weekly. I have not had a negative thing to share in quite some time. But this was noticeable.

The plant way delayed departing by 3 hours. It was an old airplane with broken seats and armrests. The bathroom made a hollering sound. A really crappy flight experience and travel day all around.

None of the airplane features were available during the flight.

Original flight was cancelled and when i was rebooked by the airline, they couldn't seat me in the same type of seat as I had originally booked (went from window/aisle to middle/middle and one was a bulkhead seat, and other wasn't in the same class)

My flight was cancelled with no explanation after I had already cleared security. I was given 4 options to rebook, only one being non-stop like I had paid for. I grabbed it. It was 4 plus hours later and then took off even later. Biggest complaint is that I booked early and had an aisle seat. They gave me a "window" seat in front of the exit row, so the seat did not decline. I weigh all of 103 #s and it was tight for me! For what I paid, I feel I was kind of ripped off. I think they should have given me the empty comfort seat for the inconvenience. There was no apology nor any explanation as to why the flight was cancelled. My guess is it benefitted Delta in some way.

Very smooth, on-time, and pleasantly uneventful flight. The team at the gate and on board were professional and genuinely courteous. The pilot kept us well updated throughout, and both takeoff and landing were steady and enjoyable without any drama. Just a good, solid flight. Thank you! 💗

Plenty of leg room, temperature was great and staff was excellent. Would do it more often.

I truly love flying with Delta. They have always treated me with the upmost respect

The aircraft interior is old and tired on this aircraft. The entertainment system never worked despite the crews attempt to reset the system.

The flight crew where really good. Better then the crew from BNE to SFO

Food should be changed in menu Many muslims travels in this airlime they need to add one Halal meal

Delayed, toilets did not flush, pilot parked to far away from Gate

Was happy we finally got upgraded in 1st class. The seat getting old. The cushiness need some improvement.

Yet another flight in which beverage and snack service was skipped. Other that that, firmly mediocre. Landed early, to gate late due to congestion at the gates. Airline's fault or airports fault: unknown.

Ineffective communication with United resulted in lost baggage. Their Baggage Tracing counter at MUC was shut down from 11:00-14:15 on my arrival. Undertrained, underinformed staff had me Running all over MUC to find someone to help me to no avail. Staff was rude, unhelpful, and unable to effectively use the systems they did have operational. They refused to contact United in any way or provide any accommodation or other resources while I waited for my luggage. This has destroyed my downstream itinerary. If they had even the slightest visibility I may have been able to reschedule/plan, but again, their staff provided nothing, and did nothing more than their website, which doesn’t even work on a standard phone browser. Miserable failure at all levels that weren’t associated with the operation of the aircraft.

Miserable. They moved my seat, but canceled the next leg of my flight. I resolved the issue at my transfer, but that resulted in lost luggage that has taken days off my schedule with no resolution. Worse, they fail to interface effectively with Lufthansa, forcing me to bounce between two equally useless help desks. The apps are unable to handle the situation, the bag dropped off the tracker, and while the call centers are polite, they do not provide written information to assist with cross-airline communication.

left on time, reasonable boarding process arrived early luggage came out quickly

I like flying first class, and United has a nice one

Teeny tiny bathrooms, crew was not realistic about when we'd arrive.

My seat tv didn’t work the whole trip. And the seat space is too small despite being seated at the front.

On the plus side, crew was attentive, drinks were cold, and in-flight entertainment selection was better than some other airlines. On the negative aide, Plane was delayed almost an hour, either no announcements from the gate crew. Biscoff cookies are gross, appreciate airlines that give a choice. Also, crew had no personality or enthusiasm at all.

Tell the crew (when boarding) to yell at the imbeciles blocking us from walking up to scan. I promise everyone crowds around and half of us (most the time I’m group 4) have to push our way through. Your staff is awesome, the public - not so much-

Baggage handling poor. Second time this has happened. My bag went to San Francisco instead of Fiji. No apology. Luckily Nadi airport staff are fantastic. My bag arrived in Fiji the next day.

Disliked having to wait a little longer to disembark from the plan when we landed in London

Food should be better quality. Video screens have poor resolution and the library of movies is poor. The other airlines are much better.

They only offered water for Group 6. Awful announcements from the Crew. Couldn't understand a single word. Barely came by for the trash afterwards. Man, I love water for a premium flight. Wow. Water in a cup.

Great. Quick and quiet and east. The breakfast choices were a welcome surprise!

We arrived 4 hours early and still almost missed the flight because they weren’t able to access one of the boarding tickets. They then sent hour bags late and we were all of our without clothing and eventually had to take an expensive cab back and forth to the airport as they wouldn’t deliver the bag which arrived late at night that day and we would have to wait until noon the began day (messing up a second day of plans). Also, all the food has dairy or pork. No vegan or even vegetarian option in the flight—even for purchase.

The comfort of the seats was great, the crew eased my child’s anxieties and the fact that I had full cans of my beverage choice was great.

First time flying with JetBlue and never again. I went to the counter to request meet and assist because I'm 74 and my wife is 79. I walk with a cane and my wife is handicapped and has her own wheel chair. I told the agent that my wife and luggage was at the entrance door. The ticketing agent said to me that they don't offer meet and assist. I need to bring them our luggage and then go back and get my wife in order to get my boarding pass. As I went back to get my luggage a Southwest agent along with a TSA agent recognized the situation and came over and took my wife and luggage to the JetBlue ticketing counter alongside the line and told the JetBlue agent to issue to take our luggage as soon as they could.

Flight was fine, price was good but food onboard was abysmal. I was on there for breakfast and lunch and dinner 845am EST to 845pm GMT and all I got was a yoghurt parfait, fruit and a piece of cake. Later snacks included an ice-cream brownie and a pizza twist. I was hungry by the time I landed and the airport amenities were closed. Not happy.

Not a pleasant experience, service was poor. Didn't like it

Plane was in bad shape. TV’s and WiFi didn’t work. Plane need a refresh. Not enough room for bags.

Everything was great. I liked the text updates so that I never miss a gate change & I have all the latest info.

No internet on a flight over three hours in this age is criminal. Staff inattentive and dismissive

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.

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

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

The flight departed more than 1 hour late. Leg room is bigger than most airlines
