Seats in Delta Main are unbelievably close to the seat in front of. Hard to get a backpack under the seat.

The flight was operated by Latam. The aircraft had a technical issue and the flight was delayed for the next day. They grounded other passengers to get their airplane assigned to my flight. Most of he ground staff don't speak English (Orlando Airport), but were very polite.The crew on the other hand could speak English and Portuguese. On board service was good.

The agent at check in and at the gate were less than thrilled to be at work. I'm not a fan of Kayak's placement on the plane. I got put in the middle seat and none of my preferences were used.

In ATL they have two sets of departure screens. Follow what is on your airline's departure board - the ATL Airport Authority departure board had completely incorrect details about the gate assignment for my flight, which would have made me miss boarding.

Flight was delayed it was hot while sitting on the plane, one engine was working on the plane until they had to do some jimmy rigging down the runway in order for the other engine to charge up. It was ridiculous

The flight was very good and the staff was very friendly and helpful!

The only thing I would say is we tried to get on a standby earlier flight, but with our fair we couldn’t. That seems senseless to leave with open seats..

Very easy to use and convenient, you can perform any action within the same portal

In a world of delays, Delta was on time both ways! Boarding was fast and efficient. Staff was friendly. AND wifi worked.

WiFi didn’t work. Flight delayed 3 hours Crew members were illiterate Seat lean back did not work.

As per usual when you Hit the UK it's a slow process through customs Not as efficient at Thailand for sure

The flight was delayed. The aircraft was unclean. Promised seat was not given due to change in Aircraft. Not one crew on ground was in a position to give any response. Amsterdam Airport is AVIODABLE Over crowded. Over Expensive. Poor Services.

It was really nice journey i personally recommend klm flight

The crew were unprofessional with a racist element. I was physically abused as well from one of the crew members

Flight was on time, staff are friendly and helpful onboard.

At the airport, terrible, I do not want to even remember it. It was too humiliating for a business class passenger.

Flight was ok but lack of communication cost me to literally beg to be put on another flight as connecting flight had departed

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.

The immigration hall in Amsterdam was understaffed, so passport checking was slower than it should be for a major airport. They need to get the automatic readers up and running for non EU passport holders. Waiting in line after a long flight feels a bit abusive.

plenty of legspace, snacks, no pull face from flight attendants when asking for a wine. Also fast transfer ability at ZRH.

Business class seating in Swiss really is just Economy seating minus the middle passenger

The flight itself was fine, but due to a snow delay my connection to Lisbon was delayed by six hours. Despite this, Swiss Air still managed to lose my luggage. Not acceptable. Someone else on the flight also lost their luggage.

Bad experience overall. Crew did not provide food for our 2 year old (even though we specifically bought a child infant seat for her and literally bought another full price flight), which was unacceptable. And we had to pay $310 each way to carry our ski equipment even though they advertise it as something that is free. Tickets were purchased the same way as usual, but they told us we had Economy Light tickets (I never elected to have such seats). Just plain manipulation and false advertisment. Very disappointed overall about this airline.

The trip was great until my luggage was lost on transfer from United to Swiss. It took Swiss 3 days to get my luggage to me though it was located almost immediately.

Horrible!! The WiFi was not working, the food was awful

We’ve never been more uncomfortable on a flight than we have on this particular one. The seats in front of us reclined so far back that when the person reclined their seat of broccoli, it almost hit me in the face and left me with literally no room to move that said I had to recline my seed in which made the person behind me upset. It seemed like the seats also would recline without even pressing the button in the armrest and would unrecline as well for that same reason, and it also seemed that some seats reclined more than others. The bottom cushions of the seat were so thin that even after one hour of an 11 hour flight, our tailbones were so sore. It seemed like an overall old airplane. It also didn’t have individual air vents and it was extremely hot the entire flight. Several passengers were commenting on how hot it was. The breakfast was some kind of flavorless triangle, puffy egg, laying in a watery bed of steamed peppers and onions and spinach. It was not appetizing at all. The flight crew was extremely nice so that was a nice thing this flight attendant. They let us try different types of Swiss sodas, which was really nice and the dinner was actually delicious but still overall given the other considerations. It was pretty much a miserable flight without basic seat comfort.

Food used to be better and comfort was not attainable after 5 hours everything starts hurting.

horrible.. they cause such a problem and my daughter 14 years old was stranded in san francisco

I can’t even the whole trip was a catastrophe

Flight was delayed by several hours and then cancelled due to weather. But Staff was very helpful getting me on a different flight. United should offer food coupons and tooth brush and paste for stranded passengers

I upgraded to the business class cabin. It was the poorest business class I have ever experienced. No access to any business lounge in Tampa airport. Seats are not comfortable. I had a window seat and had to step/crawl over the next seat. Food was mediocre and service below average for business class. Bathroom location was ridiculous. No place to wait. I cannot believe I paid this kind of money and will never fly Lufthansa Discover again. They really should reimburse me somehow.

Boarding was disorganized. The door to one to the toilets wouldn’t lock. The plane was shockingly cramped, and clearly used for domestic flights due to the menus for items to sell domestic travelers. United should be ashamed of its small seats, tiny unclean toilets, and money grubbing stance toward services, compared to Lufthansa, Emirates, and most international carriers United is awful.

Was never allowed on and not refunded the full amount of the ticket plus charged a $300 processing fee.

Terrible. Lost our luggage for 4 days. Did not advise passengers there was a strike in Barcelona Airport and had zero personnel on hand at airport to advise passengers on where to go to file claims. We had to fend for ourselves. No assistance at all other than an online claims submission process that we had to find out about on our own.

Lufthansa cancelled our flight from Los Angeles to Naples Italy on March 10 for scheduled flight on March 12 Very stressful experience trying to arrange alternatives. Will never fly again with Lufthansa

Everything could have been better. What needed to be wrong with United went wrong

The staff was bit rude when I asked for an extra drink after one beer, asked for one wine glass.

Very good, i got two seats for myself, and was comfortable with the blanket i got

I hated the FRA Airport. Confusing signage, including the path to Immigration and Security It seems that the airport grew haphazardly over the years. I have been through multiple WW Hubs with much better experiences.

Boarding was orderly, pilot and flight attendants were nice, entertainment options were good, and low sodium meals were quite tasty.

The whole experience was excellent, O can say out from Miami the best airline to travel with for any European destination. Since the ground staff to the inflight crew attention was great, service on board 10 of 10. Finally the 380 is very confortable and nice to travel.

All crew except 1 were excellent. When I asked assistance with business class seat conversion to a bed (not being familiar as never used before but have numerous times with other airlines) crew member helped very reluctantly. I should have told her that business class seat conversion is totally different in each airline such as Delta, New Zealand Air and United. Sorry it was my 1st time with America Airlines. Now I know, I won't bother asking assistance in future.

1st class seats NOT REALLY 1st class or business class but like premier economy. Should be listed as such or named something else. I have flown 1st class with other airlines and they are nothing like it at all.

The seats in Premier Economy were very comfortable. The food was better than average. The way British Airways handled our seating was atrocious.

Worst airline in the world. They downgraded me from business class to economy with no compensation.

Flight delayed, connection was not at gate listed and so missed, staff were rude at Heathrow, phone tree stupid and difficult, took me 21 actual hours to reach my destination. Almost lost my hotel reservation after walking in a strange city alone after midnight because they would not put me up in a hotel at sfo or heathrow. I will never fly BA again and will tell all people and Instagram followers never to fly BA.

Overall ok. Best part has always been the sundae dessert.

Check-in in SAN was long. ORD was good. Flight delayed On board crew was ok. No warmth or personality. LHrR barely made connection

Even if you wait for connecting passengers you should not be an hour late departing waiting their luggage. Your passengers may have connections in the other end and you harm them.
