All was good. I think the back of the plane should be boarded first. It would be faster. Minimal waiting time behind passengers loading their carry on baggage.

All was good. I think the back of the plane should be boarded first. It would be faster. Minimal waiting time behind passengers loading their carry on baggage.

This was my first time flying SAS and used them for 4 flights. The crews, flight and communication was outstanding. I flew premium economy and was extremely impressed by their SAS lounges. I will 100% ise SAS again. Everyone was so pleasant!

I upgraded to economy plus and it’s so worth the price. The crew is exceptional and the food is pretty decent. I would definitely fly with them again.

The flight was on time and loading was fine. I really disliked that all drinks other than coffee or tea had a cost. Deplaning was also an issue as people did not wait for those in front of them to get out before they pushed forward

I paid for wifi and it worked about a total of 5 min. Feel ripped off

I couldn’t make it to the airport for my original flight due to bad weather; roads were shut down, buses and trains were closed. Since the plane wasn’t cancelled, I still had to pay $720 to change my ticket.

Overall, this flight team did a fantastic job. They came often with the water, coffee and tea. There was no meal choice in coach, but the lasagna lunch was decent. The sandwich snack just before landing was tasty. The baggage bins were large, so no trouble holding carry on luggage.

Good friendly service and food - The seats in business class are old, too hard and not very comfortable.

My seat was not the one I paid for, the crew was very curt, and the cabin was extremely warm.

Boarding the plane outside in the rain was a pain. Very safe flight

Perfect timing, perfect departure, lovely crew on the ground and in the air.

Good flight. Take off a little late but make up the time

Everything’s went straight forward, no issues, good service and friendly crew

Left on time and arrived on time both ways, thank you

The flight was 45 mins delayed but the crew provided water and necessities like tissues

Cheap flights as you expect with Ryanair. I would take cheaper flights over entertainment and comfort for short haul travel. Main issue is usually delays at airports. In this case we landed roughly 2hr30 later than planned due to earlier delays with the plane. Not the worst I imagine

We each paid for 10kg checked in luggage. Flying out there were no issues sharing one case (20kg). Not so coming back. Additional £48 charge and unable to provide an explanation of why it was ok on one journey but not the other, or indeed what material difference it makes between 2x10kg cases vs 1x20kg case. Scam, and appalling from Ryanair.

Easy process and good flight experience The food good be better

I didn't like. The seats and the floor were very dirty and it is not the first time

Unfortunately didn't realise how far away Frankfurt Hahn airport is from Frankfurt the city. Outbound flight was delayed by 2.5 hours and no communication at airport, just a whisper emknating through the packed crowd ready to board at the gate as someone read out an email they had received. All rather poor and pathetic

They cancelled our ticket, gave us no warning, they reissued it 4 days prior to trip and it was cancelled again when we got to the airport- very stressful, the flight was overbooked so they drove us across Milan to malpensa

I've done hundreds of flights in my life, and this flight was one of the best I've ever taken, From beginning to end, everything went smoothly, professionally, and with a smile and friendly attitude from all employees I interacted with. The food was delicious (and free), as were the drinks. There was just a genial and effective way in the way that British Airways organized the flight -that reminded of days in the 70's, 80's, and 90's, when flying was a fun, and exciting adventure. I enjoyed and had confidence in the abilities of the flight crew, I'll be flying British Airways several more times this summer. Thank you so much for the great experience! Cheryl Olso

Some how I got “offloaded” even though I had my boarding pass Food was horrible Staff were nice and cheerful No headphones were provided

Terrible! I missed my flight to my final destination and British airlines and American Airlines keep pointing fingers on each other’s. Nobody wants to take responsibility

Overall, terrific service, accommodations, and experience. Only reason comfort was rated lower was because it was difficult to keep a comfortable sleeping position for the overnight flight, but I also had an economy seat.

Very Stress free Lounges were superb. Crews were caring. I loved it.

The FA told me that the dinner was vegetable curry which turned out to be vegetarian (tofu) which I don’t care for but that was the only disappointing part of my trip.

Entertainment catalog certainly needs an upgrade to include better and latest content. Food was not good at all - they need to cook something edible. Five starts to the crew and on tim performance of British airways though!!

Very cramped seats in economy, difficult to get comfortable with your legs and feet and back. The seat width is ok but I’m average size. Food is HORRIBLE. Crew is friendly. Delays and very tight connections made it tough for navigating. We would have missed our connecting flight if it wasn’t delayed too. The terminal transit was slow and normally every 10 minutes before 8pm, after 8 pm is every 30 minutes!!!!! No free wine or drinks!! Below average attitude.

The flight was nearly empty so we were welcomed to spread out and relax. There was some turbulence but nothing too scary. The crew was lovely!! They engaged in conversation and were very friendly! The food is terrible!!! Horrible wooden utensils, they barely pierce the food or cut anything. I sat in basic economy and was very comfortable. Customer service at the desk was polite and helpful.
