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!

Flight from MEX to ATL had to divert to Tampa. When we got off the plane, there were non directions on what to do. Nearly 30 minutes just standing around. Finally told to go through security with no boarding passes, and turned away. Then told to to go back. Took forever to leave Tampa for ATL. Missed my connection to Harrisburg.

This long-haul international flight was the most comfortable among any of the same kind of flight operated by an American-headquartered airline - second to none!

I've flown several other airlines, and Delta is really on top on things.

Outdated equipment in disrepair, wifi inoperable. Broken seats, taped air vents, generally poor condition, the 717 showed its age and lack of upkeep.

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)

Safe and stable made me sleepy and I slept and dreamt 😂😂😂😂

Food was really mediocre for premium economy in comparison to other airlines… the crew was nowhere to be found… 14 hour flight…

I don’t like that an equipment change caused my seat to change from 23A to 44A. The boarding was also delayed. The crew were excellent, however and very attentive. The food was not bad.

Worst airlines either. First leg was delayed because of crew not available. My connection was missed so they booked me automatically the next day! But, impossible to get anyone on site, web site does not let me access my reservation anymore, confirmed by useless agents over the phone. My 2-leg trip with part in business class arriving at 4:10pm ends up in an awful 3-leg arriving at 9pm the next day with no way to even choose the seats and of course at the very end of the plane. I can understand problems arrive but the way Air France handle it is just unacceptable. You are on your own. Apparently getting you to your destination is the only thing they consider their duty. The customer experience and fatigue is none of their concern. And I have a status with them. I will reconsider my priorities when flying with Air France and encourage everyone to do the same.

Our flight crew were terrific. And they handle a difficult passenger with finesse.

Excellent, Lima to Paris. But Paris to Amsterdam, delayed, missed my flight and KLM treated its missed flights passengers very badly, terribly bad. No hotel accommodation given. Passengers were told to find their own hotel accommodation and claim at reasonable rate and left the booth and literally with armed Police Officers listening to passengers complains. For three hours, after moving by Uber from hotel to hotel and calling and booking online, no hotel was available. I had to return to the airport and seat/sleep on the benches, suffering the cold, and rats running around until my new allocated flight the next day. It was the most terrible KLM treatment even seen and being a Business Class passenger. Still mentally suffering to date as a result.

3 hour delay but out of their control. App said I get vouchers but when I applied for them, they were nowhere to be found in my account

I bought business class tickets but the seats are exactly like economy with no comfort seats nor an empty seat next to me provided. Very poor, low quality airline.

Not great - seats were very narrow and food was terrible.

Some of the crew was sassy and not super helpful. The food was okay, but it seems like they were all unprepared compared to my flight I did from JFK to Frankfurt

We missed our flight. There was not enough time built into the layover to get through immigration, customs, bagclaim, bag rechecking, and the long trip to another terminal and gate. Kayak really screwed up. We took the bus up to Wisconsin and then were picked up in Brookfield by private car. It was lucky we didnt miss the last bus out.

We were in premium economy seats that appeared to be locked in plae, No reclining. My aching back.

I don’t understand how they charge as much as they do for such a poor experience

Lufthansa flight LH04414 from Munich to Washington DC, was fine. Efficient and safe!

I wish the plane had pod seating for business class. I had a window seat (8K) and I had to climb over the person sitting on the aisle when I needed to get up. Also there is no partition between the seats for privacy when sleeping. The Asian airlines have much nicer business class seating. Their seats are wider for better comfort when sleeping.

Bumpy ride, not Lufthansa‘s fault. Crew managed a situation over a back rest to far down well. It was two iles behind me. The person putting the seat down, against the other person’s knees, was quite rude and belligerent and needed to be told in a no nonsense matter to stopp. Male flight attendant did good job.

Patrick and the whole crew were amazing! Hope to have this team for all my European trips.

This review is based on 2 things: 1. The lack of hygiene on the plane. 2. William - the head flight attendant. The lack of cleanliness on the plane upon arrival was appalling. Being given a sanitizing wipe upon boarding of the plane is shocking when you consider the cost of a business class flight. UA expects me to do their job and clean all the bread, food and debris left from previous guests. Does this sound normal to you. The seat, the food table and the sides were full of crumbs, chocolate and dirt. When I told the flight attendant they just gave me more wipes so I could clean it myself. Secondly, William the business cabin head flight attendant was so busy flirting with a couple in the front that his attention to the other guests was minimal. He continuously asked them if they were ok or if they needed anything and it didn’t matter if the rest of us needed anything. And if you are the lead attendant shouldn’t you be checking if the bathrooms in business class are clean and needing toilet paper. There were 2 bathrooms in business. Halfway through the flight the first bathroom was closed and the second bathroom was dirty and had no toilet paper one hour and a half before the flight landed. He needs additional training on prioritizing things. He should care less about flirting and more about his work

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

The flight crew was kind, flexible, and accommodating. The seats on the plane were extremely uncomfortable.

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
