Delta One is extraordinary. I fly business when somebody hires me. I just wonder why there is such a chasm between business class and the insanely inhumane and nonsensical coach. The seats are not large enough to fit even my tiny wife. We fly 10% of what we did because we don’t want to pay 5-10 k but for $400 it’s unbearable. It seems like the accountants took over and made stupid decisions. Screw in 20 extra seats and make it so unbearable that people fly 90% less. Just put the damn price up and put some proper chairs in. But business, yay.

Timing, quality of service, promptness and courtesy of the staff

It was last minute due to weather - considering - it was amazing! Good smiles, friendly staff and they were making sure we knew what was going on when and where.

delta last minute gave me a boarding pass for a different flight with no confirmation that they were changing it

The service from the flight attendants were of supreme quality. They greeted and treated everyone with a wide smile. This is totally absent nowadays. Kudos to them!!!!

Excellent flight and got us around tough weather. Only issue was seat TV did not work and crew tried to reboot.

Very large passenger too space from my own seat. Arm board couldn’t be lowered because of his size. It wads very uncomfortable trip, as the flight was full couldn’t move anywhere having back pain because of the position in which I was the entire flight.

was sitting in the jet bridge for 10 minutes in -20 degree weather waiting for my bag

Very convenient considering that is a non-stop flight, but the Aeromexico still has old model planes, so the entertainment was very poor and the space for carry-on luggage was very limited.

Flight taking off must have been behind, because there was no pre-departure drink for first class like normal. Also, person in front of mine’s seat got stuck in the as far back as it normally goes position for the whole flight even during landing, flight attendant unable to fix it. Gate was not empty when we arrived, but that is MSP’s fault since was overdue for push back, not Delta’s, so had to sit on tarmac for a while and international flight so then still had to go through customs. Flight crew was excellent throughout though!

Food has been disappointing in both legs of flight to india

Great staff great experience, made a 2 hour delay very bearable

Great staff, great experience, made a 2 hour delay very bearable

Food was the worst I’ve had on a VA flight. Normally it’s a lot better

I was my pleasure to fly virgin on my birthday for my first solo trip ever 🫶🏼

These are one of the older seat arrangements facing away from the windows! Not particularly convenient sets. No storage spaces. NO COAT HANGING HOOKS. Inconvenient business class seat compared to any other airlines of similar class. Staff are excellent! Extremely professional, friendly. Food is good too.

Overall, flight was excellent but check in was very slow for Premium Economy. Economy queue was shorter but we weren't allowed to use it.

The staff was not very polite but the flight was very very nice and comfortable and the entertainment was great

Great crew - old style upper class seats on the older fleet now feels dated

Premium economy more comfortable than economy, but not by much. Did was awful, do not try the omelette. Flight crew were helpful. Flight was delayed by over an hour. Overall but bad, arrived safely and thank God.

The flight attendant use 1.5 hours to answer my call. My dirty food tray was unattended.

The flight was completely full. Crew was not happy. Everyone was rude and brusque. Travelling with an arm in a cast and seating in the first row of economy cabin (in front of the separation) I needed help retrieving my tray for the meal. A staff member literally threw the tray on my lap, without helping to take out the tray. Boarding was messy, with 300 people waiting in an encloses space with low ceiling. I will try to avoid AA next time I have a long flight.

No enough space plus only allowing one laggage instead of two like other airlines.

Qatar airways ,boarding arrangements at Hamid international airport could been better

AA should improve their in air internet & entertainment options. Seems unreasonable to charge $20/hr and should have some form of free connections. The entertainment options are also pretty limited, movies are outdated and the series only show 3-5 episodes.

The business class seats are dated and uncomfortable. The space is bare minimum and there is absolutely no privacy. For $4K, this is not what I expect.

Flight, food and crew were all good, friendly and very satisfactory.

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.

Staff's did their best to make everyone comfortable and I appreciate them for it

Ring in first class for an overnight flight, there was no blankets nor pillows for first class customers.

Terrible. They canceled our early morning flight after midnight on the day of and had no available flights to rebook my family on for the next 72 hours. Yet they still had other flights that were not cancelled from JFK so it couldn’t be based on the weather. It felt like they canceled the flight based on it not being profitable enough for them. I am not interested in traveling with the again. The absolute worse customer service and lack of accountability.

Horribly rude check in at airport, worst in 25 years of flying. All over a simple issue they could have googled to resolve.

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.

Our flight was delayed 5 hours, very disorganized, bad communication, confusion. Only good thing was the crew.

1) No pilot available for 1 hour 2) no room for most passengers careyon in overhead—-> stowed below 3) when we landed we had to wait 45 min. Before docking at gate as gate was not ready

It was good. I prefer JB over other airlines.I just wish we had headphones for the films, but other than that - good.

we were delayed because of some safety check that wasn't done or available

Qatar Airways only had spicy meals on the menu in economy class. You might want to get food in the airport before boarding.

Friendly crew. Poor food service maybe due to full flight. All in all, you get what you pay for.

very difficult boarding process - aggressive passengers not the friendliest crew

My touch screen at my seat wasn't working, the films BA advertised on the website for this flight were not available, and the plane was a little dated, food was good and the staff were good, just let down by the aircraft facilities.

Did not like the seating configuration at all with 2+3+2 in business class. Lacking total privacy and comfort

Check-in experience, for business call please provide a premium experience

Lost my luggage, ran out of food choices in business class, ground crew was completely unapologetic.

Excellent. The crew and flight were great. Checking in was easy and everyone was very helpful.

Entertainment devices on A380 need to be fixed, the seats might do with updates.

Everything. Employees offered to help me because I had to use a cane.

Check-in and boarding were great. On flight staff were rude and disrespectful. Paid for extra room and found it incredibly cramped. Bathrooms kept in poor condition. Overall negative experience.

Great seat in premium economy, great food and drinks throughout lots of in flight entertainment. 1 hour 40 min delayed flying out , 2 1/2 hour wait at passport control in tampa

My seat cushion was poor. The cushion was compressed and was uncomfortable for such a long flight.
