All good- I love BA and the professionalism of the crew and pilots.

8.0 ExcellentAnonymous, Apr 2024JFK - LHR

All good- I love BA and the professionalism of the crew and pilots.

Great flight- smooth, nice crew, nice clean aircraft, departed a little late but arrived 10 early.

Sorting on line would have been appreciated Onward information on flights missed No ability to get seating arranged before we got to gate Very unfriendly at gate

The flight was Finnair but there was no indications anywhere that the checkin was for Finnair also. There was no one to ask. I think at a minimum they should list the code shares so people don’t stand in the wrong line for an hour.

I booked the flight with Finnair, which made the arrangements for downloading a boarding pass unnecessarily complicated. I wouldn't do that again. Instead I'd book direct with AA.

Flight ok, but me and other two passengers didn’t have connection with the entertainment in our seats. So, no movies, no games, no music… for 9 hours. The crew just told us that there’s nothing they can do but I noticed during the flight that there were empty seats, so they could have offered to us to change seats. Customer service could be better.

Had a nice flight to London on BA will fly with them again in the future

Finnair cancelled my flight 12 hours prior to leaving for Helsinki. They stated there were mechanical problems. I had to scurry around to find a new flight that would meet my needs for arrival in Helsinki. Luckily I was able to find alternate transportation through Lufthansa/United.

I’m very disappointed, to fly into an airplane for 10 straight hours, and not having a TV even though when I put the ticket I was told that I will have entertainment for the TV. Very disappointed.

Helpful steward. Allowed me to move to some empty seats and I was able to get some sleep. He also had milk for my tea. Americans don’t realise that cream or half and half ruin tea.

Bathrooms weren’t too clean. Onboard entertainment was light. Other than that everything was great. Food, service, comfort and crew. Although it was hard to understand the crew announcements.

I had economy plus and it’s definitely worth the price. The seats are so comfortable, so much space, great large TV screens, and you get fed often. Really decent food (although other fish was overcooked.) They do need better movie choices. The crew is the best. Super friendly and accommodating. So much better than most American run Airlines.

They lost my luggage. Tromso in winter without warm clothes is not fun.

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

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

Last minute cancelation, though a substitute flight was found I could not pick my meal or seat. The hotel offered didn't have working air control or shower.

Old plane with terrible business class seats - good food and service. Boarding was a joke with business class boarding last.

The flight was cancelled early on and messed up the whole vacation and hard to get a refund from Kayak as they owned the ticket and of course they did not believe that SAS cancelled the ticket. Definite bad side to third party. SAS had rescheduled but overlapped the connecting flights. That did not work. Flight was cancelled long ago but Kayak still has it. Like it was taken? Bad IT ? Or all assumptions and no follow up which is the whole IT world. It needs to wake up and be more efficient. Especially as the world is going, there will be no freedom to do anything. And we will be living like the Middle Ages. Yeah, go read up on that while you still can.

It didn't happen. SAS csncrlled and it was very difficult to convince the 3rd party they did. Not good on the 3rd party program. I don't think they trust their customers, much less being able to help them. I have had several nitemaes using 3rd party this trip and WILL NEVER use 3rd party again.

I child in Buisness cried almost the entire flight. And I had a conference to attend but couldn’t sleep because of that, which was the main reason for getting a Buisness ticket. Also the food is not as good as before. The sheets underneath is also not there anymore. The staff was nice.

Another 35 min delay landing No apology no communication or acknowledgment about this

Try to humanize onboarding and take AI out. It's embarrassing and useless

I was ver pleased with the service all the way through

Overall good experience. Polite crew. Good foodandentertainment. Seats are small and bit congested though.

Used to love Lufthansa, but Rowe are too close together in Economy and passengers are allowed to recline their seats so far back it is impossible for those behind them to even reach for carry-on essentials during flight - except for meal service when flight attendants ask for seat backs to be raised, we can’t sleep on planes so this flight was most uncomfortable ever! Rod Rose

I ended up buying (for $340) "extra space" seats because I my flying partner was given a STY boarding pass, leading me to conclude that she was on standby and that we had to buy seats on the flight. I later learned that the flight was not sold out and that we could have gotten on as usual. To be honest, I felt swindled.

I'm Canadian. I have the unfortunate experience of pretty not having the choice to fly with them. THEY ARE TERRIBLE.

bad seats, meager food quantity. bread not fresh. Hollywood films lack entertainment.

The process overall was pretty seamless, and the crew were very friendly (especially Michael). Considering we booked expecting Lufthansa and the flight was operated by United, it was still a very good service and journey overall. The in-flight entertainment was great, with lots of quality options. One slight negative was that I had selected a vegetarian meal prior to flying, but received a vegan one. I think there should be more dietary options as it meant I missed out on some food that I would have preferred (and it seemed like the standard meals and snacks had a vegetarian option anyway). There was also a group of people who were moving around a lot and being generally disruptive at the quietest part of the flight, when the lights were off and most people were sleeping. I would have appreciated staff stepping in to encourage them to be mindful of others). Towards the end of the flight (which was very early in the morning in both time zones), the lights suddenly came on and breakfast was served. In my opinion, this was too early, and everyone was rudely awoken from sleep. After breakfast was cleared away, the lights went off again for about 45 minutes, allowing people to sleep some more. Then the lights came on again for landing. It seems like if they had served breakfast later, the lights on-lights off-lights on shenanigans could have been avoided, and people could have slept longer (and staff could have rested longer too).

You only get a chocolate square and small bottle of water.!

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

Tickets were cheap but it says no where that food was not included, I travel Austrian, Swiss and Turkish airlines all the time always food is included, never flew Norwegian again

Pros: "I made it to my destination"
Cons: "I have never got in almost 13 hours of flight and was not even offered glass of water or any food!!! Norwegian flights are not providing any beverages or food and when I asked they told me I should have added food options on my booking???? That’s the most unbelievably weirdest and inhuman flight I have ever took. Will definitely make sure not to do same mistake ever again!"
Pros: "Staff at Rome was great. Crew was excellent. Plane was magnificent."
Cons: "Service at CheckIn was the worst I've ever received. The staff exuded no compassion, empathy or interest in trying to help me. I had to buy an extra checked bag and instead of giving my options clearly, they gave me a run around (do it online, call our customer service, refund your ticket at our service desk - all false). I did not appreciate that lack of competence or interest and as such will not be transacting business with Norwegian again. Furthermore, the crew on the airplane did not check on me or my row of passengers the entire flight. No water, no cookies, nothing! This was the worst display of airline service I ever seen!"
Pros: "Puntualidad y amabilidad en la recepción de equipaje"
Cons: "Pésimo servicio en la llegada a Bergen. No solo no llego una de las valijas, sino que no había nadie en la oficina de reclamos, nos hicieron recorrer todo el aeropuerto hasta que no les quedó otro remedio que ayudarnos. Mala disposición de los empleados. Lo mismo con la recepcionista del buró de información turística"
Cons: "It will be nice if economy class get at least a bottle of water!"
Pros: "Seat comfort , modern plane"
Cons: "The boarding process was ridiculously disorganized . People were not boarding according to their group numbers and there were many unnecessary delays / hold ups . My baggage was lost for over 4 days (it still hasn’t arrived on October 24. I landed on October 20). With little to no communication on it status or refund on all the baggage fees I was made to pay.While the crew was pleasant , price point attractive and plane modern, These factors are enough to deter me from choosing this airline in the future"
Pros: "The crew was excellent! Nice leg room!!"
Cons: "I would like to have free access to coffee and tea. I understand the cost of meals but a complimentary beverage would be a welcome, inexpensive treat!"
Pros: "Cheap flight"
Cons: "Cabin crew announced they will be dimming light for landing but that was not the case at all. They kept on turning the lights to a different color which was uncomfortable for the eyes. Pilot did a really great job on letting us know if there is any turbulence and when to expect during the flight. Flight attendants had no social skills, they acted like robots only there to serve for people who ordered. They should really change the way they perform because they are catering to the whole customers on the flight as opposed to only those who ordered their meals."
Pros: "Happy crew, efficient. Friendly. Everything on time or early 5*. Appreciated no fuss of hand luggage size and weight (as on others) Keep up the good work!"
Cons: "All perfect, none"
