Great boarding, great short flight but no entertainment whatsoever. It was supposed to have wifi but that did not work.

Great boarding, great short flight but no entertainment whatsoever. It was supposed to have wifi but that did not work.

Transfer at CDG to connecting KLM flight to Amsterdam was a NIGHTMARE. LONG WALKWAYS, NO MOVING WALKWAYS, POOR signage, Have to take a train & No staff visible to help navigate the maze. AVOID TRANSFER AT CDG AT ALL COST.

There was fog in Amsterdam so many flights were delayed because of the weather. Air France knew that the flight would be delayed by two hours but still boarded the plane on time. Instead of letting the passengers wait at the gate we were crammed into the plane. It was uncomfortable. No refreshments were given. I couldn’t charge my devices onboard.

I tried to upgrade to premium economy anis seat online during the checkin process. The payment didn’t work due to a technical glitch on KLM’s website. I wasn’t able to change my seat unless I called Amsterdam. Since I was in Canada and there’s a time difference this wasn’t practical. So when I arrived early to Ottawa airport my seat wasn’t available and I could only get a middle seat in premium economy which isn’t great. These middle seats are priced at the same rate as an aisle seat which makes no sense.

Seats were comfortable crew members support was very good but AVML ordered or selected by us needs a lot of improvement.

Transavia flight, was booked as KLM but i couldnt select seat or access boarding pass with KLM at all. Crammed seating and very no frills experience all around. First and last time.

Transavia flight. Couldn't select seat or anything prior to flight. No connection with klm systems. Seats are very crammed. Extremely no frills.

Seats were nice and comfy. Crew was polite and attentive. Business class is awesome and worth the money.

The IFE was quite old, but it worked fine and the content was good. The cabin crew were excellent and the food was as also very good

It’s chaotic at the bus stop outside of the airport because of the Uber meeting point. You need to be alert and look for the KLM bus which is not branded or labeled. Incorrect information was provided to go to gate 28, when in fact the bus was at gate 27. On the plus side the bus left early and arrived early to Ottawa.

Should have had business class line in immigration. Food quality suboptimal

The staff were wonderful but the seats weren't very comfortable for a bigger guy like me.

we were delayed from Athens to Abu Dhabi by an hour and a half, so I had trouble connecting the flight from there to Bali. It could have been done had they waited even 15 mins. There was another lady who was in the same boat. By the time we were half way across the terminal, they have actually already issued different flights for us to go Jakarta then to Bali. Not to mention the inconvenience of waiting over 4 hrs at the airport and the subsequent inconvenience, we did not arrive to Bali till after 800pm the next day, which means I paid for the hotel for nothing when I could have been there before noon the next day! There was little explanation. It was just as well I needed some assistance getting around, otherwise the 2 of us would have been completely lost! Not going to fly with them again!

Likes: on time departure, new plane Didn’t like:very poor quality food, very limited entertainment.no amenity kit etc.

The seat was like there is no leg space....there were no proper option for food in the airline. It seemed like the airline was at brink of bankruptcy. The crew was helpful except for a few.

Boarding was efficient, had to check in cabin luggage. Seats were narrow, food was more in quantity, received cabin luggage on the luggage belt which was fine.

Bad. Flight was very uncomfortable with narrow and shallow seats, very little food and water. I will not fly etihad again.

Boarding catastrophic let alone have to claimb the plain rather than using jetway. 5.5 hr delay leaving had to do stop in Lgw for a new crew which further compounded the delay. Connecting flight would not wait and had to pend a night in a hotel. Curiously my seat would not go full flat.

The flight was delayed which cause me to miss my connecting flight in AbuDhsbi airport.

I did not have a good experience in both flights of Etihad. First of all, when I was booking the flight, there were two options. The first option was a cheaper flight with longer layover (9 hrs), or a more expensive flight with shorter layover (2 hrs). I booked the expensive flight with shorter layover because I wanted a more comfortable trip. A few days before the trip, Etihad informed me that the departure time of my first flight will change 7 hours earlier, leading to an 9 hour layover, without giving me another option nor reimbursing me for the extra cost. They didn’t even send me an apologetic email for this change. Regarding the flight experience, I would rate it as mediocre. This is mostly because the pilots of both flights did their best to give us the worst approach to airports that I have ever experienced. In the case of the first flight they had to aboard the landing and took off again right before touching the landing strip. The captain said that it was due to wind conditions but the second time the pilot followed the same direction as the first time to land the plane.

compared to other business class journeys, the hard product is okay..but the service of the staff is underwhelming. They are very senior and seems only to care for the colleagues they upgraded to biz and to themselves , I was not offered food before after 1 1/2 -2 hours, and the menu had one dish and the food was not that. And i could not get the breakfast.. just coffee and a croissant. i have type 1 diabetes .. luckily i had my own food. was low in sugar after sleeping and woke up 55 minutes before landing .. not able to get food anymore !! so bad business experience!

LAX to Copenhagen was very nice…business class…great service and comfortable seats…great value…Copehagen to Barcelona…business class was normal coach seating…a little cramped…box meal….good service

Had recurring problems with the touch-screen entertainment system repeatedly making up inputs, resulting in the movies randomly jumping forward and backward. With the lack of proper controls, it was also difficult to get back to where the movie was up to. These phantom inputs were so comprehensive that the system even changed the language setting. Despite a schedule 6.25pm boarding time, it was announced in the Delta lounge at 6.15pm that boarding for the flight had started, so of course everything started to head down. While the gate continued to show a scheduled boarding of 6.25pm, it was 6.32pm before boarding actually started. No, not significantly different, and we ultimately ended up landing well before time (and landing time is arguably more important than exactly when boarding starts). Seat comfort was fine, although only a small nook for personal items, food was satisfying for me, and crew was pleasant.

Staff was fine. But plane offers very few free services.

Entertainment system caused delay. But order was restored within one-hour into the flight. Service was good.

It was my wife and me traveling together. We purchased more expensive Economy Plus tickets, but the seat selection was not available, although this was the main reason for buying the more expensive tickets. When I called SAS, I was told that the seats could be selected once check-in is open, i.e., 30 hrs. before departure. On the inbound flight, I could check in only the first leg (Boston-Copenhagen) but the system would not allow me to check in for the connecting Copenhagen-Split flight. On the return flight, I was not able to check in and, therefore, select two seats together at all. I even received an email from the SAS stating that the check-in was open but when I attempted to do it, the system would not allow it. Trying to get help by calling SAS customer service was no help at all. Although there are signs at Boston Logan Airport implying that there is a Scandinavian Airlines lounge, there is not one. We were sent to Delta Priority Lounge where we were told that it is for business class passengers only, although the terms of Economy Plus state that the fare includes access to a lounge. The seats and the legroom were no different than standard economy cabin seats. On the flight to Copenhagen, my table was broken (not unfolding completely), so I had to hold the food tray with all the food in one hand while trying to eat with another. Overall, it was definitely not worth it paying for the Economy Plus tickets. Based on my overall experience, it is very unlikely that I will consider flying SAS in the future.

Pilot made us late 45 minutes with no explanation, missed our connection, they didn’t care

The flights from EWR to Stockholm and from Copenhagen to JFK were great. Love everything from SAS

First off, numerous things were misrepresented. When we purchased the Economy Plus tickets the fare allegedly includes access to lounge. At Logan Airport where the signs points to, there is no longer SAS lounge. We were directed to Delta lounge, which is located at the other end of the terminal. When we got there, Delta reps told us that it is for SAS business class passengers only. The advertised seat selection 30 hrs prior to departure did not work online. When I called SAS, they told me that it was more than 30 hrs before our connecting flight in Copenhagen, although it was less than 30 hrs before the departure for Copenhagen. Customer service representatives would not provide any assistance. The tray table in my seat was not fully unfolding to be able to place the food tray on it. Therefore, I had to keep it on my laps.

When we arrived in Bergen and opened our suitcases, we were shocked! We checked 2 of 3 suitcases and the contents of these 2 suitcases was completely wet!!! It was raining in Oslo and Bergen, but not a hard rain. It seems that someone had gone through our suitcases. There was even sand in the suitcase such that everything had to be laundered when we got to Bergen! We had plastic bags in our suitcases and they had been opened and the interiors of the bags were wet!!! Our valuables were all in our carry-on so nothing was actually stolen. What happened here was unacceptable! There is someone working for Scandinavian Airlines who is not honest and really messed things up for us. Not so sure I would fly SAS again… Marna Skaar

Not what I expected for the last leg of a $5100 business class experience. Boarding was a nightmare. The flight was delayed and I had to keep checking my email to ensure I was at the right gate since the airline or the terminal had no clue until 15 mins prior to boarding. Food was gross, limited drink options.

My flight was delayed d the gate was never updated inside the terminal. If I hadn’t checked my email I would have missed my flight. Also, I paid a total of $5100 for my flight to be. Business or first class. My final leg of my flight from Heathrow to Frankfurt was not to standard of what I expected or experienced in the previous legs of my trip.

Liked - efficiency of boarding with 2 jetways. Checkin was with kiosks with helpful and plentiful workers to help with the process. Munich airport security was very automated, efficient and effective. Free wine and beer! Cons - food was only okay in economy class. Plane bathrooms could have been cleaner.

The jollof rice and fried plantain. Communication could have been better.

The flight was at 6:10 am to early. No coffee or anything else offered. To 👎

Had to rush to catch the plane because our flight was late leaving Moldova.

Overall experience is mediocre and the food was poor. I would avoid Lufthansa next time.

was having emergency they keep dalying the flight I miss hull my trip and united airline charges me &100 for bags and I spent more thin $320 at airport for my family and when I get back samthing Daly my flight in muc I lost flight in Chicago I spent another &220 at Germany airport for no reason I should get refunded it’s very hard when total off us 7 people buy food at airport

Always delayed, always. luckily our next flight was delayed or we would have missed it. Cabin crew were great and informative, ready to help.

We bought tickets with Lufthanza from Kayak for flight operated by United..

Easy and quick check in, clean and nice seats. Overall excellent experience.

Late in leaving the US. Late in arriving in UK. 2 plua hous on ground in UK before leaving. Late in arriving in Spain. Didn't get our bags until the next night.

No gate was assigned until 5mins before boarding so left us running to find it. Then over 2 hours on runway. First due to weather, which was understood, but then over 1 hour for something that wasn't really a problem. Poor communication between ground control and flight crew. The flight crew was wonderful. British airways will be on list of airlines to travel again.

Food and entertainment non existent as we were only in the air 25 mins so totally understandable

Experience was probably the best I’ve had on BA for a long time. Only thing is A380 is old now and it needs upgrading. The en re attainment screens are very small and the touchscreen barely works.

Staff member at boarding gate was rude, and more than once!

The issue wasn’t necessarily with British Airlines but was a reaction to their delayed flight from Miami to London on Aug 18. Due to the delay out of Miami, we missed our BA flight with Aer Linguis on the 19th from London to Cork, Ireland. The attendant in London was helpful and rebooked us for a flight later that same day ($120). However, she failed to mention that as a result of the missed flight, our returning flight was also cancelled and the rebooking cost was $451. Disappointed at the lack of communication between airlines and between the agent and the customer.

What a great flight that was. Leaving from the small London City Airport, which was easy and convenient to get to on public transport, The flight was slightly delayed, but no big deal. The crew was attentive and served the light sandwich meal, a snack and a soft drink with a smile. The seats were ok, but the same like other budget airlines. The onboard luggage allowance was good and way better and hassle free compared with budget airlines. Well done B.A. and keep the good work up 👍👏

Abby who was the crew member in my cabin had some serious attitudes. May need some training and some kind of diversity training.

I had paid for my family to sit together on the plane. When we got to the plane this wasn't the case and we were separated. meanwhile the lady sitting next to me told me how she didn't pay and were all sitting together
