I feel the service staff do not treat American customers well. I also feel there may be discrimination against minorities.

I feel the service staff do not treat American customers well. I also feel there may be discrimination against minorities.

Yes avoid JFK airport at all costs. A horror to navigate.

No free Wi-Fi. I have SkyMiles but not a high status, having an account has been enough for Wi-Fi on other flights, but this one was going to charge me to use it. Also turbulence was really bad toward the end, but I didn't count this in my ratings since I know Delta cannot control the weather - it's 2026 and lack of WiFi alone is enough for a poor rating.

My daughter always gets sick when we order the gluten free meal option. Internet didn’t work as advertised.

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.

The legroom was lacking and the entertainment system lacked adequate selection of older films. Modern films are generally not very good.

Perfect airline, super friendly, great service, tasty food. Would fly again.

The flight attendants were wonderful - one man put my carry on in the bin for me. Very attentive service. Loved the blanket and pillow waiting for me in economy. Food was excellent which is a surprise given the reputation of any airline food. Wine was fine with the meals. Delighted with the new movies - flight went by very quickly. I would definitely fly Lufthansa again.

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.
