Connection flights should be spaced out farther because too close I missed my connection.
Connection flights should be spaced out farther because too close I missed my connection.
Definitely a southern flavor. Cordiality was evident even though no drinks or snacks were served.
On time! There were plenty of airport employees who were able to keep us moving in the right direction. The crew on the plane were professional.
Left /arrived on time. Decent seat space. Like the wifi/plugs and entertainment. Windows and tray table were kinda gross. Attendants didn't start snack service til 40mins before landing. Two rows before us, captain came on to say there's turbulence and recalled staff to seats. So, no drink/snack. Later, attendants didn't stop to see if we had trash nor even look our way. Felt invisible! Almost all pilot announcements were not only unintelligible, but so quiet. We had no idea what she said.
Average seat comfort, a drink and chips were provided, early boarding because we checked a carryon at the gate was nice. Ticket pricing shenanigans, including fees to pick a seat, check a bag, and get food onboard - evidence the industry is reinvigorating last century’s strategies- destroys the experience before one ever arrives at the airport. It’s difficult to recognize any value or sustain loyalty in the end-to-end process making air travel more drudgery than pleasure.
Gate agent was unhelpful for handicapped boarding. Flight attendant seemed untrained.
No service flight that took 5 hrs and a stop at an unscheduled airport. Crew and pilots did their jobs
Clean planes and not take my comfort class seat away.
The crew were efficient. The pilots seemed professional. It was a bit chilly in our seats. The sheet provided weren’t very helpful.
Weather caused a long delay, but the efficiency and updates from the pilot were helpful. We were able to make our connection fortunately.
Outstanding even though the 330 was one of the oldest in the fleet. The difference was the attentiveness and responsiveness of a really experienced flight attendant. For airline food great variety of interesting choices and good tastes supported by a good wine selection.
The crew were unprofessional with a racist element. I was physically abused as well from one of the crew members
Empty seats next to me - wish it had been for a longer flight!!
Terrible last row seats many seats available but no offer to move to better seat
Delay on my previous leg, had to run to catch my flight. But that happens. Overall ok.
At the airport, terrible, I do not want to even remember it. It was too humiliating for a business class passenger.
They forgot to serve food and the crew was very unfriendly. Never experienced such a bad KLM flight. Usually fly from Toronto. New York was different.
Couldn’t get boarding pass in SLC even with help from a redcoat, so had to find a desk in AMS to get boarding pass. Technical problems so not sure why. Very inconvenient. The KLM app is not as user friendly as most apps. Also had to wait almost an hour on the tarmac for a fuel truck, which caused us to miss a connecting bus in LUX.
Over 1 Hr delay. No APU so no AC on ground. Plane was hot during boarding and then they closed the doors over 20 minutes before engine start so interior of plane was steamy hot and stuffy. Could have been helped by opening doors until ready to depart.
First of all we couldn’t check in online, then we learn at the airport we were on stand by for KLM’s mistake of overbooking. The seats were not comfy at all. Our luggage got lost.
Everything is good except the seats are tightened no rooms for the legs,
The flight crew was exceptionally friendly and helpful. Also the seats were comfortable and roomier than many other airlines.
The plane's pilots, including the captain himself, thanked me for the flight. I know it's just marketing, but it was really nice to see these people. It's a great idea. Airplane food is never "good," but the entire crew and flight organization were top-notch. I really liked Delta, and I think I've traveled all over the world, and that was something new for me. Maybe even the old planes, the B767, but next time I have a choice, Delta will be my first choice. Thank you, a satisfied passenger :)
Middle seats SUCK!!!! I paid more money than I should have because of your terrible site Kayak.com. I'll try to use your competitors going forward. I am so disappointed you would play off business class.com as business class seats
The boarding was efficient. The entertainment system was a bit unstable but Air France has a good selection of movies.
They lost my bag and I still haven’t received it yet
Communication on the delay, rebooking and how to get a hotel was poor. Mails, airport check-in and transfer desk said different things.
Not consistent with the food quality (I mean taste not freshness)
Food was really mediocre for premium economy in comparison to other airlines… the crew was nowhere to be found… 14 hour flight…
Our flight crew were terrific. And they handle a difficult passenger with finesse.
Vegetarian food options were pretty tasteless. Gob of rice with absolutely no protein, barely any vegetables, and poorly seasoned. Food was the major disappointment of an otherwise good flight experience. However, food is a differentiator on long haul flights.
We were an hour and a half late, which caused my rental car company to cancel my reservation. We had no car, had to take a taxi to our hotel, and then a taxi back to get a new car the next day. Sometimes lack of on-time performance can end up costing the passenger a lot of money, none of which is covered by the airline that operated the late flight.
Overall good experience. But seats were small and uncomfortable for the price. Good entertainment, staff friendly and attentive.
Flight was delayed no information given really . No food whatsoever on the plane . I think you should be able to put that on the app so people have a chance to buy food bring it with them . They said plane was very busy on way over but there should be enough for both flights as we pay full price for the service. No information or very slow on the app about the delays . Staff were lovely it’s not their fault so company not fare to passengers or staff .
Smooth quiet flight take off and landing both excellent. Food was mediocre. Boarding at gate was disorganized and unacceptable.
My only complaint is that during my 8-hour-long flight, the flight attendants came around with the coffee and tea cart twice instead of the alcoholic beverage cart. I would rather sleep on a plane than rush to the bathroom to take a dump. I asked the flight attendant if I could have a beer instead of coffee or tea. Unfortunately, she said the bar is closed. That tells me that she was too lazy to get me a beer on the plane. I was not happy about that.
Caring & friendly crew. Most important: got us SAFELY to our destination!
Friendly flight attendants, decent food if you can eat dairy.
Very good trip. Nice clean aircraft. Helpful and friendly crew.
Other than Air Lingus not loading one piece of luggage on our flight from Dublin to Barcelona, with it arriving one day after we arrived in Barcelona, all was good.
First the flt was delayed over 2 hrs bc of plane mechanics that should have been handled better! No text or email was sent so only found out at the airport so there we sat for 5 hours! THATS RIDICULOUS! The gate area was filthy! No agents showed up till hr before so no additional info was given-waited online for 15 mins while the gate agent chatted and got together then given last seat in back of plane!! No priority for senior or anything-took attendants over 2hrs to serve drinks and snack-WHY are they not served together? By time snack came needed another drink! Worst service in my life!
Since we started at syr the service, crews, and flights were just excellent
All the TV screens in my rows was non functional . The map shown for an international route was antiqued..
It was fine for what it was. It’s not luxury travel but it was efficient, for the most part. Having my carry-on transferred into luggage however, was unwelcome.
We had better-than-average leg room and I loved the access to shows and movies. During boarding, we could not hear the agent even though we were close to the boarding door, which was kind of scary when we realized that half of the passengers had already boarded. Also, the entertainment was awesome, but I could not hear the movie as well as I would have liked, because my headphones were crappy. It would have been better if I could connect my own ear buds via Bluetooth or if JetBlue provided headphones.
On time, friendly attendants, quick wheelchair assistance and help checking in bags. Also appreciated change in seats, more forward to make it easier for my 97 year old mother to board and exit the plane. Thank you, JetBlue!
Flight did not have onboard charging and TV screen flickering.
I was seated next to an autistic child who was out of control and had a child behind me kicking my seat for most of the trip. I will never fly JetBlue again. Ever. I don't care how cheap it is. It's terrible.
Boarding process was terrible. No assigned seat until the gate, then a long line to get seat assignment.
This was the first flight I've taken since pre-pandemic. I was pleased with how orderly the boarding and disembarking went. The seats were comfortable. I loved that there was no "first class'. The attendants and passengers I met were all very friendly and welcoming.
