Crew were excellent and the bar service and chat fantastic. Cheese board delicious. Amenity kit good, very disappointing not getting pyjamas on this leg of the flight and needed to reuse from earlier flight.

Crew were very good. Food service was a little slow and disappointing not having on demand dining and only 3 options. Amenity kits and pyjamas were excellent.

No kids provided. Instead we were told to have contacted the airline that we have kids and require kids meals. We were not the only ones who inquired about kids meals. It’s odd. Emirates and other airlines give kids meals as standard and before the adult food comes out. The rice in our meals was gluggy and under cooked. The chicken was also raw. Sadly not the best experience with Finn Air. The hostesses tried to compensate with the snacks and drinks but missed the mark by a long way. Especially when paying Emirates/Qantas prices

Hospitality is good. Should improve on buggage handling because l lost a suitcase. Layover in Dubai was too long , 6 hours

Emirates First Class is always a treat with Caviar and service is always personalised.

Delayed and missed connecting flight. But Emirates took care until next day flight. Thank you

They should resume the fast track for business / first class passengers

Premium Economy was not up to my expectation relaxation wise. The chair doesn’t extend enough. It is not economy but not spacious enough to relax and sleep. Food and services were excellent but I am not very keen about food in general.

Everything was great but the food portions and quality was awful

First time and very memorable, the finest flying experience ive ever had

I appreciated the vailability of wheelchair services for persons with mobility issues all the way up to the aircraft. What could be better would be the food choices.

Initial booking was confusing and had to get new CC issued.

Excellent service. The personal adaptation of menus and the individual timing of service of them is fantastic.

Lobster starter in business class was not good, tough, served cold, and without butter. Movie selection was missing latest releases, did not offer older classic, high quality movies

The flight was operated by IndiGo and not Qatar, which is a budget airline from India. Nevertheless, the flight was uneventful.

Not sure how we end up with American Airlines instead of Qatar Airways. From Philadelphia to Qatar they boarded us then they asked us to unload. After 30 minutes later they board us again. The inside the plane it was burning hot and we were sweating like crazy. Crew members are absolute rude. The way they served the passengers were horrible. One of the crew members hit my knee with food cart and kept going. I was holding an ice pack for almost 2 hours. I am still with the pain.

Terrible experience resolving missed connection after flight was delayed. 3 hour queue at transit desk, not enough staff, no organisation, worst ever flying experience.

Worse fight I ever take since I start flying , still have even made home , and crew abandon us half way home . No water no food and no even anyone to answer our questions

The Achilles heel of the experience with Qatar Airways is the Doha Airport, especially for travellers arriving into Doha and not transiting. This airport suffers from being ambitiously big and the immigration into Qatar being overly time taking. At the end of my particular flight in which my travel was ending in Doha, the plane parked at a very remote terminal, from where it took me 30 minutes to arrive just at the immigration counter, with fast paced walking and the time on a train inside the airport. Then, at the immigration counter it takes up to a minute or more to process each tourist visitor,due to time taking face and finger scanning processes and langugage barriers if there are questions or information to be exchanged verbally with the officers. If several planes have landed at the same time, it is not unusual that one has to wait 45 to 60 minutes in the immigration queue. In short, the frustration of arriving at Doha takes away all positive vibe of the airline, as the airline and the airport are heavily intertwined and are marketed together.

It was ok, not much more can be said, as long as airlines/aircraft manufacturers insist on cramming in as many seats as possible....best of a bad situations, seats are simply too uncomfortable to sit in for more than a few hours. Lack of flexible headrests not a help on long overnight flights either.

We booked a business class ticket via Underpricer. Somehow they screwed up our ticket from Abu Dhabi to Ahmedabad. We will be hesitant to book again with them.

I was charged $604 for a bag that weighed 17 kg. I was given three different prices until they landed on the most expensive one and didn't budge a penny. It's ironic and a bit enraging because the total cost of my ticket was $468. I've traveled the world and never experienced these kind of prices for only one piece of checked luggage.

Etihad charged me for 2 check in bags. On Kayak search results price was showing 2 check in bags were included. Kayak need to reimburse me for these additional charges and metal agony and distress. Thanks.

In Colombo when I-drop my baggage Sri Lanka air line crew not polite way talk very rude

Same problem place in the middle so small Im 1,85 m so not good 👍

The WiFi was not compatible on both my phones (Vivo Y30 5g and Samsung Galaxy A32) with up-to-date android software.

Did not provided with option for class upgrade. Staff at gate was not able and willing to accommodate with class upgrade, eather with plenty empty spots in business and first class.

Old plane, old entertainment system. It wasn't working throughout the entire flight. I was offered to connect to their system via Wifi to watch on my phone. Crew wasn't very helpful except one lady who turned the experience around.

Stewardess was attentive and was actively roamin to check the passengers on the biz class

It was worst flight ever of 26h. Poor service and seating. Flight from Abu Dhabi to Islamabad service and seating was worst ever. No tv extra.

From the checking, ground handlimg was very poor.seems new personal on duty,people qho suppose to be teaching them didnt see around.new people may mislead passenger, as of flt info boards, not give proper info.even informatiin counter people dont get uptodate info.makin big ques, totally disaster.guests were not happy about it.even boarding to aircraft some BC class pax sent to aft staircase, some aft pasx sent to front door.poor ground handling.may need to improove.

Nice crew.flight delay fromBKK for some ground prep issue I guess, crew serve well to guest, and respect to guest as well. As usual AC is old,and nt much comert in compare to other rehional airliners.other than that.all good

All good, on time, depart.only bad side was, airxraft is too old to be in business.hope ailine will manage somethinv somewhat.all good

Flight was on time.food is as usual good.Aircraft is old.old A320, seats aithout any display.crew serve well

Was good, comparatively. A330, with good crew set.on time depature. And crew try there best, to make thing efficient.

Spesific ,Crew and cabin manager, look after all pax on board despite being in a old A320 equipment.Got free seat upgrade as well,but old style seats, no much comfert on it.But food and the spesific crew, was amazing.maintain airlanka standerd.the cabin manager, who was so much keen,keen operate as per SOP.

Was got free upgrade, on old A320.aircraft is out dated kind of.bt service ,cabin manager, tried there best.and food was excelent.

When flying from Indian Sector, should be more prepared with Indian food

KAYAK Real time status update is not accurate.the flight inbound rejected and go around.and came back and land. Delay abt 30 min.still shows ontime.track ur self if u wana real time.and cabin crew s are nicer. Aircraft is jst ok.old airplane.and in midflight ,seems have some compressor issue.airconditioning was nt work properly either.I could litarary see guests were cheking if AC is working.bt on landing it start to gv cool.which probably some one intentionaly kept .which was so bad.even breathing was bit difficult.otjer than that.for me all ok.

This leg of the trip was smoother than compared to the initial trip. Sri Lankan Airlines still have much work to do to improve the overall travel experience.

Not only were the aircrafts spacious, but the crew was friendly and efficient. I was so gracious for the included meals on the longer flight (8+ hours).

Smooth trip no turbulence which is always a bonus for me lol! In cattle class so an element of being a bit squished (but not as bad as other shorter haul airlines) smaller plane than the one we flew out on and entertainment system wasn’t as modern but still definitely passed the time. Lovely crew x

The check-in baggage belt was broken (which is understandable) but what was surprising is they would check you in, give a baggage tag and then you have to drag the baggage to a different counter at the end of airport. No vegetarian option in in-flight meal. British Airways remains the worst big name airlines and always my last option while booking.

Decrepit planes, poor business class layout designed to maximize revenue, no decent movie selection.

Entertainment did not work from DC to London. Was not able to check in online during my return journey from Mumbai to London. Food was good!

The to flight was excellent but the return flight the seats seemed not cushioning enough.

⭐ 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, Sara 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.

For a business class ticket the service was very mediocre. We had to ask for coffee after a meal and the service was grudging like we were putting them out. The leg from BOM to LHR was especially bad and the toilets had no water. It was disgusting. Looks like self service is the new model for Business Class. No Thank you. I will look elsewhere

The boarding process was very poorly organized. Too many people had way to much carry on and resulted in loading overhead bins being the gating factor. Time for change.

I do not understand how BA takes coach seating and has people paying for business class. There is no leg room, seats don’t recline and no entertainment to be had unless you brought your own.
