It wasn't an AeroMexico connect but SAS, I dunno where that AeroMexico info came from. A word to the wise - do NOT get an international connecting flight into Eurooe at Copenhagen that has less than an hour layover between flights, or you'll never make it. You'll need to go thru immigration at the airport before catching your next flight, which takes some time, and then it could be a good half hour walk or more over to your next gate. Kayak lined up flights for us with only a 45-minute layover and it was literally impossible to make the nect flight ... I figured if their robots thought it woukd work it should be ok, but don't trust the robots! Had to wait for the next plane to make it to our destination.

Crew members were excellent. The seat wasn’t the best as well as a food options.

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.

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
