Terrible last row seats many seats available but no offer to move to better seat

Delay on my previous leg, had to run to catch my flight. But that happens. Overall ok.

Delay and had to run between flight to get my connection due to this delay but besides that the overall experience was ok. I arrived with just an hour of delay.

Couldn’t get boarding pass in SLC even with help from a redcoat, so had to find a desk in AMS to get boarding pass. Technical problems so not sure why. Very inconvenient. The KLM app is not as user friendly as most apps. Also had to wait almost an hour on the tarmac for a fuel truck, which caused us to miss a connecting bus in LUX.

The immigration hall in Amsterdam was understaffed, so passport checking was slower than it should be for a major airport. They need to get the automatic readers up and running for non EU passport holders. Waiting in line after a long flight feels a bit abusive.

Short flight so it was okay. Nice crew, all very pleasant and professional. We were near the back in row 27 so just as we got our drinks, we started our descent so had to drink very quickly!

KLM remains a quality flag carrier airline which maintains its standards whilst all their competitors are lowering theirs.

The baggage drop-off in Stuttgart is bad: after online check-in you cannot use the automated baggage drop off as indicated on the website. You can use the terminals but have to cue to 1 of three open and slowly working counters to drop the bags. took about 45 minutes wait time.

Our first flight was delayed so we missed our connecting flight. However it was easy to book a later flight on their app.

My flight was delayed by 6 hours then I missed BOTH of my connecting flights, I then had to stay in the AIRPORT at JFK because soooooo many people also suffered from missing flights and there was no hotels available. I would like to be compensated for this experience! I had to stay in the airport for over 16 hours!

All reviews good because...flight from BWI to London ,economy seats was miserable. I usually book 1,step up from economy but this would have added 1500 bucks 1 way. Bit the bullet and upgraded for retun flight, otherwise all ratings would have been rock bottom.

Great. It was awesome to have boarding from the front and back of the plane as it made the process go very quickly

It was okay. The airplane was a little smaller than a flight from Thailand to Helsinki.

Wish that everyone would board the back of the plane first. Also let kids on first. The gate wasn’t open at arrival and we waited 45 minutes to takeoff. They made up for time in the air.

This was an absolutely exceptional flight. The flight attendants were extremely attentive and very friendly. They seemed to go out of their way to make us comfortable and to make sure that we had everything we needed., We were in business and were very happy with the size and the details for our pods. We would definitely recommend Finnair and will definitely be flying with them again.

We had an excellent trip with Finnair. This was our first time and we’re very pleased. The only issue was with the boarding - it was a little bit confusing and needs a little bit of streamlining.

Crew very lovely. Arrived an hour late due to bad weather. We were given new tickets to an other flight but it could have been organised better, so we did not have to run through the whole airport to.

Flight delayed over an hour. They said they would hold our connection but then did not.

Major problems checking in at Alaska counter. They could not find our booking code because it came from Finnair.

Do not use KAYAK or Finair for future travel. Unless you purchase the tickets directly from the airline, you were going to have a difficult time checking in. Kayak canceled my flights twice and ended up causing great difficulty in me getting back from Europe because they double sold my tickets between American Airlines and Finair. The event caused significant delays and led to me having to rebook my flights.

Cut out the nickel and dime pricing for "seat selection" and baggage, To do this on an international flight is just mind boggling. Seriously, why treat customers this way??? Nobody wants these hidden extra fees and everybody hates them. Also plane was too warm and no air vent, and water dripped from the ceiling at one point,

It was a fairly old plane in which you couldn't buy an internet connection.

Scandinavian was perfect. Nice A350 with an on time departure and an an experienced crew. What a difference from TAP.

The staff were great, the food was good. I just hate being crammed in a tuna can for 10 hours cause I can’t afford a better seat.

1) SAS sent me emails that i could check in but that was just a waste of time because traveling to the us i actually had to check-in at the airport. 2) SAS evidently does not care about vegetarians as it does not offer regular veggie alternatives in the transcontinental flights.

Great logistics and timeliness as we arrived quite early. Flight smooth and fast. Excellent entertainment. Plane itself was a bit tired and the crew mostly indifferent. Baggage took forever but that’s on CPH. Would use SAS again for sure.

Baggage was mis-handled; food and grocery items in the baggage were damaged.

I didn't book special seats but the ones I got were great. The food wasn't good but on par with other airlines

Service, food was outstanding. They make every effort to make sure that your long flight is as comfortable as possible. The only reason I did not rate them excellent is the way they handled our cancelled flight. They were great about re-booking except for the hotel. A communication breakdown ensued regarding who was booking the hotel for our overnight stay: the city where the flight was cancelled or the city where we were going to lay over for the night. In the end, neither of them did, so we ended up doing it ourselves and were extremely lucky to get a room at all. Given that, I still would not hesitate to fly with them anytime.

I paid extra for our seats on the way coming back from Stockholm to New York the seats were changed and it was totally waved. This happened to three more passengers.

it was great the cabin crew were polite and detail oriented.

Paid for exit row at the back of the plane. Window seat with lots of leg space. Food was inedible (as usual). Brought my own.

Efficiency of staff, and comfort and cleanliness of aircraft was all great. Maybe a hot drink without payment at that time in the morning would be good!

As expected. Would have appreciated a 3-day headsup reminder as a reassurance that all is well.

The plane was late (as was my flight out from Birmingham the day before)

I ended up in Lufthansa to Zagreb because of our delay

The flight was delayed by an hour. Made the connection uncomfortably tight.

Food was great but they didn't clear my meal tray for 3 hours. You'd think they could check though the cabin now and then.

Entertainment system is old, touch screen isn’t working properly. New movies should be added atleast once a month Should provide toothbrush and toothpaste at least when asked.

When we went to the lounge they told us to go into the main lounge and not the full business class section, later they told me that Lufthansa wont pay the full fee to alloq the business class passengers entry to the nicer sectikn where all the other airlines nusiness class passengers go into. Very poor arrangement.

Nice lounge but had a 5 hour layover which is a lot

Flight on time and priority boarding worked. I travelled economy although business was available as no flights are cheap these days and at least with BA loyalty card I get a baggage allowance for nothing. That made the flight comparable or even cheaper than the ‘budget’ alternative. As for catering and entertainment - not on a BA short haul economy ! At least we were offered biscuits and water! Catering for economy short haul has been reduced to the minimum - no tea or coffee or other drinks than water (from a large bottle with a paper cup on offer). They will say this is better for the environment, which it is, but proper waste management is still needed for empty packets etc. so actually it’s a money saver.

Audi visual not working for a whole group of seats in first class. How does a plane leave the main hub in such poor condition? How much that we can’t see so immediately is also compromised?

main meals are horrible but then you dont fly for the food

It was good. Couldn’t Check in online and select seats

It was great. Enough space and room for legs . Great service to.

⭐ British Airways Review — A Journey of Highs, Lows, and Lessons ⭐ I recently flew Business Class round-trip from Boston to Mumbai with British Airways, and my experience was a tale of two extremes — from disappointment to exceptional service, and then back to inconsistency. Boston → London: A Surprisingly Poor Start My journey began on a disappointing note. On a 6-hour Business Class flight, I was surprised to discover that there wasn’t a single proper vegetarian meal option available. I was offered a few bakery items only after repeatedly requesting something to eat. The flight attendant shrugged, offered no solution, and eventually — quite literally — threw some bread at me after much delay. This was not only disheartening, it was extremely surprising given my wonderful Business Class experience with BA last year. I stepped off that flight genuinely hungry and had to make a mad dash to the lounge just to get a proper meal. London → Mumbai: A Complete Turnaround The next sector restored my faith in British Airways. The entire crew was warm, welcoming, attentive, and genuinely caring. A special shoutout to Phiroze and the entire team serving the Business Class cabin — their professionalism, hospitality, and thoughtful service were extraordinary. They truly embodied what makes British Airways a global leader, and I am deeply grateful for the experience they provided. This is the BA I know and love. Mumbai → London: A Strange Meal Schedule This sector was generally fine, but the meal timing was puzzling. Lunch at 10:30 AM — for a Business cabin — felt unusual, and most passengers, including myself, barely touched it. The rest of the service was smooth, but the scheduling definitely needs a rethink. London → Boston: Mixed Experience Again The flight itself was decent, but the Business Lounge at Heathrow for this leg was a letdown. Arrived during lunch hours: no hot vegetarian options available Lounge area: dirty dishes everywhere Even after politely alerting the staff, the dishes were ignored and left uncleared For a premium cabin passenger — and at one of the world’s busiest international hubs — this was disappointing. Overall Impression My journey with British Airways felt inconsistent — two great sectors sandwiched between two that fell short of the BA standard. When BA is good, it is world-class. When it misses, the gap is noticeable. I genuinely hope the airline takes this feedback as constructive insight. I continue to believe in British Airways, and I commend the outstanding crew on the London → Mumbai sector — they were the highlight of my entire trip. With a little more focus on vegetarian meal availability, lounge service, and consistency across crews, BA can ensure every Business Class passenger experiences the premium journey they promise.

We were in business class and I had seat # 1. This was a night flight and after dinner was served, lights were dimmed and I went to sleep. The crew were loud and noisy so I didn’t get much sleep. I expect the crew to enjoy themselves but would Appreciate some decency in staying quiet while the passengers sleep

Have travelled business class with other airlines who profess to be the best in the world. They can however not beat the service and comfort that BA provide.

Great on board entertainment Tasty food Cattle class obviously crammed but not as bad as shorter hall flights
