Airline reviews

Flight was cancelled without notice or any reason given. I found out coincidentally when i was checking the baggage allowance on the app, When contacting the airline, the only option peresented to us meant we lost a day of our weekend getaway. Had a lot of contact with airline prior to flight, trying to get them to resolve the issue. We could have traveled the first stretch ourselves but the airline refused to accommodate this. The airline outright refused to be forthcoming in agreeing to alternatives that would let ut keep the date we had booked, and so a third of our holiday effectively vanished. This meant a lot of hassle, changing hotel nights, activities etc. Furthermore and after the flight, customer service refused to answer our complaint unless we used their very restrictive online form, which gave us no chance to properly explain what our issues were. They have of course denied our complaint, and so i have to bring the matter further. If you have an alternative airline to use, please do. SAS treats its customers as a necessary evil.

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.

Really good. Everything went smoothly. That's what I hope for when I'm on a long flight, especially with multiple changes. Thank you SAS.

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 flight was delayed 2.5 hours from Lisbon to DC so we missed our connection to Seattle that would have arrived at about 9 PM. The agent initially said we had to stay overnight in DC and there were no other options to put us on to get us to Seattle. While on board I discovered a flight via American he could have put us in but by the time we arrived in DC that was sold out. We were then put on a flight to San Francisco that was also delayed then arrived in San Francisco and our flight to Seattle was also delayed so we ended up not arriving until 2:15 am. Our son could not pick us up so we ended up having to pay over $100 to Uber home. This is the second trip with United that the flight has been delayed causing us to miss an evening in Las Vegas and we were given nothing.

MY FAMILY'S LUGGAGE WAS LOST FROM ROME TO BARI. I WAS THE ONLY ONE THAT RECEIVED MY LUGGAGE FROM ROME TO BARI. AFTER DEPLANING IN BARI, WE WASTED A LOT OF TIME AT BAG CLAIMS LOST AND FOUND REPORTING THE CLAIM AND PLEADING FOR THE BAGS TO BE DELIVERED THE NEXT DAY. WE WERE TOLD THAT IT TAKES 3 DAYS MINIMUM TO DELIVER. MY DAUGHTER AND MY GIRLFRIEND NEEDED THEIR PERSONAL THINGS AND WE WERE STAYING 3 HOURS AWAY FROM THE BARI AIRPORT. WE HAD TO DRIVE 3 HOURS TO THE AIRPORT TO COLLECT OUR LOST LUGGAGE THE NEXT DAY. WE ARE NOT HAPPY WITH THE EXPERIENCE

There were no facilities in the middle of the aircraft and premium economy was not allowed to use the business class facilities, and had to share the only two toilets at the back with economy. The upgrade to Premium was definitely not worth it

Our flight to Rome, Italy was cancelled the day of and we were never informed. We only found out because I was trying to get into my husbands account and called to get his account number. Had to pay more for worse seating on another airline.

The economy seat was much less comfortable for an international flight in terms of recline and moving space when food tray is expanded. Per entertainment, it would be amazing if I could connect my Bluetooth headset or ear phones to the entertainment screen. Or provide in-flight wifi to connect directly from my own device.

We were a little disappointed to not be able to complete check in online without uploading pics of passports. Also we have KTN's and they weren't on our boarding passes when we got to security. Had to trek back to counter to have them fix.

Excellent service in Polaris class IAD to ZRH. Arrived rested and well fed after the overnight flight.

It's a short hop. My carryon was checked at the gate, I didn't have to drag it all over the airport. Excellent wheelchair assist.

Was great in general, try to respect time and excuses when slight changes have been made, appreciated!

Terrific in every way. On time, professional staff, multiple movie options to select, great food and drink.

The food on this flight was better than what we had getting to Rome. The flight was comfortable and the staff was great. One of the staff members was a stickler about the blankets in the aisle, which I get, but still. Overall, great flight and will fly with them again!

Our screen kept turning off ...3 times...had to get crew attention to turn it on again

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

Bulkhead seats should not be an extra charge. They are extremely uncomfortable. And we missed our connecting flight due to slow luggage retreaval.

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

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.

Had a few open seats and could use it for a great rest ful journey

It was very good. Service was friendly and efficient, and food was good.

We left 1.5 hours late therefore missing my connection. The airline didn’t give vouchers.

Food could have something without dairy, I couldn't eat anything. Tv for both seats was malfunctioning. They have one bottle of ginger ale for entire plane.... and I paid extra for these seats...very disappointed
