Round trip flight to Canada and back to the US was smooth and efficient.

Round trip flight to Canada and back to the US was smooth and efficient.

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.

Spanish speaker flight attendants were incredibly rude. A male flight attendant named Allen, grabbed my bag out of the overhead bin and moved it without my permission. When I asked what he was doing, he informed me that the overhead bins were public space? It would be easy to ignore this comment, as you don’t know the whole story, but the flight attendants were militant and rude. Delta, you can do better!

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.

My business class seat was inoperable and unable to recline for 10 hour flight.

Excellent service. Friendly and attentive flight attendants, can lay back in business class and be pretty comfortable, and delicious food. Flight on time departing and arriving.

I will say the same as my previous comment. Great job over all! From 1-10, ten be the best… I will give 9!

had to wait 1 hour once boarded. so we were 1 hour late arriving.

They are absolutely impossible to get hold of. A death in the family caused us to delay our departure. They are impossible to get through to and after waiting 41/2 hours I was told they would not consider helping us. They cancelled our return flight and have not reimbursed anything. I strongly urge readers to consider a different airline.

A lot of snacks and provided on request by traveller. Preferred meals which were on their menu were not always sufficient for those who wanted them. We were told 2 different items and offer which we asked for were not offered initially. We rejected the 3rd item given as a substitute for our initial choices which we didn't want and so we didn't accept it. Eventually our initial choice was offered. During service of coffee and tea, the crew member didn't offer us and moved back. Luckily neither of us wanted tea at that time. Crew members must avoid behavior that may be suggestive of discrimination

The crew was awesome. My husband fell while traveling to the WC and got a head abrasion. The crew helped him greatly and a physician that was also on the flight checked him out as well. They all get an A+!

Online check in and seat assignments are terrible. All 4 flights

Cabin was kept very hot and it was uncomfortable. Entertainment system did not work at my seat. Crew and service is fantastic

Extremely bad BAD BAD BAD. NEVER TURKISH AIRLINES EVER AGAIN..PIRATES COMPANY.

Typically great service from Turkish with comfortable seat and amenitie, good food and great attention from staff.

The connection time from the flight to Stockholm and the flight out of Stockholm was too short. Due to a knee injury, I almost missed the second flight. From deplaning at E5 to boarding at F69 takes more than 40 minutes.

All went smoothly. That's what I want on a long flight.

I expected more, but they will nickel and dime you for everything. I did not enjoy flying with this airline.

Curious and efficient service ! First time flying with SAS and very pleased!

I wish they have given us explanations for the delays. And the rebooking process in Copenhagen was too long. I had to wait about 4 hours before they assign me a hotel. From there the handling process (accommodation, transportation and meal) was excellent.

Our trip plan from Kayak stated we were flying SAS. That was not true. The first leg was a Delta flight. We wasted 25 minutes before finding out to check in with the correct airline. Then our SAS flight for the second leg arrived 25 minutes late, and our third leg flight with SAS closed the gate knowing the flight delay was SAS’s fault, and that this flight would only be backed up 5 minutes. The final kicker was that between Delta and SAS, they lost all our checked luggage.

Since our earlier flight was delayed, we missed this flight and were rerouted on Lufthansa 2 days later.

Scandinavian Airlines is terrible. Flight was late. Lost luggage. Rude flight attendants. Terrible experience.

The flight was very cold, and the seats were rather uncomfortable. The food has been better on our other SAS experiences. Most significantly, the luggage with most of my wife's personal items and clothes didn't make the flight. Hoping for a quick resolution, but no real opportunity to speak with a Human has us concerned.

Ancient aircraft (busted armrests, poor cabin temperature with no option for passenger control). Garbage everywhere. Risible checking of safely conditions on landing. Also, late.

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

Service was excellent. Flight was only about half full, which meant we had tons of room to stretch out. Boarding area was nice and well organized, flight attendants were super friendly and attentive and we loved the 3 snacks!

My flight was cancelled, but it was not Kayak's fault. Kayak did require me to pay for the ticket twice to two different venders who paid Lufthansa. Kayak/Lufthansa owes me for the first booking I made first was fraudulent on the part of the subcontracting ticket seller. There will be litigation over this issue under the current passenger protection laws.

flight was half full, plenty of empty seats, was able to lie down across 4 seats, food was good, arrived on time

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

Terrible. Our flight was completely cancelled with no options to rebook until 4 days later.

Generally good. Not their fault but the design of the Boeing 747 had seating supports directly in line with my legs. So my legs always had to straddle this support which caused body misallignment. Such poor design from Boeing. There was no USB port for me to charge my phone. The screen touch control was very poor.

I like crew. They are friendly. The flight was delayed to take off for 1hr and that caused panic at Houston Airport to catch connecting flight due to security check delay. If it has reached on time I would have sufficient time in collecting bags and security check

How about changing the personal out to more friendly human beings? This team was pretty arrogant. No fun!!

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

A shout-out to the flight attendent, Lauren, who was the main person assisting me. She was amazing - perfect balance of bright, cheerful, engaging, yet formal

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 flight from Dallas to madrid was delayed for 2 to 3 hours, the flight back from Dallas to Sacramento was fine , but there were 5 gate changes within the span of 2 hours, last one was in a differny terminal. Flight and crew was okay

I was downgraded from business class to economy class with no compensation. American Airlines is absolutely the worst airline for international travel. They treat their business class customers like dogs.

OK, except for a cabin attendant's lack of attention.

efficient. on time. cabin crew were very professional and very nice to deal with. would definately fly BA again.

It was great overall. A few slight improvements could be made on the onboarding process at the Gates with announcements and clarity of communications (both at the gate and in flight). The movies in the entertainment options could be improved for bollywood, hollywood.

I alrady responded to this request, and expllaned at length that this was the worst flying experience in my 77 years. I will NEVER fly BA again.

Airbus A350 is poorly designed for wheelchair users and reduced mobility passengers. The angle of the pods makes it awkward to transfer. I was able to but I have ab stability. It could be a real challenge for people with more severe mobility impairments. You'd think Airbus would have come up with a solution for this or thought more about us disabled folks more when designing this aircraft.

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