Excellent business class seats, service and food. No airline does it better.

The only negative thing was boarding a Copenhagen-bound flight in Toronto. The middle aged woman at the desk gave me some bad time, claiming they wouldn't allow me to board the flight, switching to russian in the process. After I asked her to speak English and explained her that I had to reroute with the airline due to flight cancelations that where beyond my contro and will be leaving the Shengen zone promptly, she told me I had to check in my small bag because the flight was full and they needed someone to give up their cabin luggage. After I refused, she told me she would have to check my bag if it fits the allowed dimensions, which it did. I understand she's not an SAS employee, I understand she needs to check the documents and also make sure there's enough room for overhead bags on a plane. What really made me mad was her hostike tone and the beyond poor communication skills. Basic politeness would go a long way.

The stewardess was incredibly rude. The gave you only one drink with dinner.

Cancelled flight, wasn't refunded paid selected seats. Poor customer service. Called airline and they didn't realize the flight was cancelled until several hours after the email notice was sent.

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

5 of my 7 pieces of luggage are missing and they cant call to find out where it is. I have to fill out a form and wait for them to mail it to me in several days (if they find it). That does not work for my travel itinerary. I need my full ticket cost refunded please.

Fantastic. The only thing - out of my six luggage one was lost in Copenhagen, however it was delivered Home 3 Days later so all great..

The crew was friendly, the flight was pleasant. Thank you for your service!

Flight was completely full January 9th? I problem i had the stewardess was bumping into me constantly walking by? very annoying.. on Austrian air I dint have this issue at all...

Amazing! Everyone was so nice and the food was so good!!

WiFi didn’t exist , seats were super cramped, lights stayed on near my seat for a long time while others were dimmed, the food/trash/drink cart hit my shoulder at least a couple of times while moving, food options were down to just one option by the time it got to my row, the utensils were garbage (knife bent at a couple of places by the time I was done eating) the spoon was very flimsy plastic

Vegetarian selection could be better. Bread was too hard to chew.

Crew was friendly and competent. Food, wine, and entertainment were excellent except the raw tuna on the flight to Split. Recommend against serving that - at least as the only option. Many medical conditions do not allow people to eat raw fish.

After arriving in Chicago, we were taxiing for 1.5 hours with infrequent and untruthful updates about the amount of time it would take to arrive at the gate. Minimally, the team could have provided timing expectations that were more truthful, especially one their original expectations were not met.

United didn’t even try to hold the flight for me. They knew I had a tight connection and when I arrived at the gate less than 10 mins after final boarding the flight had already gone. The gate agent wasn’t even notified that I was on my way. She was told I wasn’t at the airport

Good quick flight on a small but comfortable plane. I'm 6'3 and had plenty of space.

The flight was delayed so we were dead tired, and after that the turbulence was horrible. I was very scared.

Wonderful. Quick boarding. Early departure and we arrived 30 minutes early at our destination. Unfortunately, when you arrive early, there is still a departing aircraft at our gate. We had to park for 30 minutes until the gate was clear. So our early arrival was not really early at the gate. Otherwise it was a quick and smooth flight. Appreciated the efficiency.

Wifi took a while to kick in and we had a maintenance issue that took over 40 mins at the gate in Washington before pulling back

Very good. Because of the delays with my previous flight, I missed my connection, but I was able to book another flight through the United app easily.

On-time arrivals and departures. Crew helpful and friendly. Yet everything costs extra: seat selection, food, even airphones!

I had no idea that my ticket only paid for my right to get on the plane. They charged me $130 for my carry-on bag because it was 1 inch too big she claimed but it wasn’t! Then they wanted another fee for everything. I had no idea that Icelandair had changed to such a bargain basement airline. I was very disappointed.

Second time with Saga Premium, everything was fab, but the entertainment centre on both my flights didn't work, plus the seat on the NY to Rek flight (Airbus) was so solid and so uncomfortable. The 737Max flight's seat was much, much better.

The most uncomfortable seat i’ve ever had on a flight

Waiting area on top of stairs before Boarding the bus wasn’t great. Took a long time to load the bus to gate.

Nice, quick flight. There were lots of empty seats so they told me I could sit next to the emergency exit where I would have more legroom.

The staff was kind and helpful. There was no food, and you needed to bring your own earphones to use the entertainment, which I didn’t know.

They wouldn’t check in my luggage even though I had one checked bag prepaid. So I took my bag to the gate and tried to check it in there and two employees scolded me for bringing a large bag to the gate. I told them I was trying to check it in and that it was prepaid, and they said they couldn’t guarantee that it would arrive at my destination but they finally let me drop it off when boarding the plane and pick it up right after exiting the plane. There was no food, and there was no entertainment.

Overall satisfied and would fly with them again. They could improve the check-in efficiency at BOS, we got backed up because it seemed there were passengers requiring much more time for check in.

The customer service was unbeatable from the wheelchair assist team to the flight attendants. The pilot also did an excellent job managing the turbulence.

Excellent experience in every way, from ground crew helpfulness, boarding experience, inflight service all the way to modern equipment. My new favorite airline. I wish I could fly with them more often.

For a no frills flight this was surprising comfortable. The crew were helpful and nice. The flight was smooth and there were no delays or issues which I haven't had on a flight in a long time. I would definitely fly with them again.

The flight was canceled by play less than 24 hours prior to the trip, and I was unable to re-book. Have not received a refund for the trip despite filling out the appropriate form.

Was was cancelled less than 24 hours prior to my scheduled departure by PLAY. Despite my attempts to rebook my travel, I encountered significant cost increases that rendered this option unfeasible. In accordance with EC Regulation 261/2004, airlines are required to issue a full refund for cancelled flights within seven days of the scheduled departure if a refund is requested instead of rebooking on another flight. It has been three weeks without a refund or an answer

It would have been better to have USB charging ports available on the longer haul Flight that one of 2 hours

Was very good Staff was great. No tv monitors tho. So long flights make it longer

The worst. No free beverages. No entertainment on an overseas flight. Not enough space. Never again.

Play is affordable! Only way we fly from the states to Europe. Left late but arrived on time

have screens on backs of chairs...offer free snacks and water

Definitely get premium economy on a flight this long if you can. Your legs and while body will thank you.

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
