Airline reviews

Could not board flight due to visa issue and emirates staff at the airport refused to help rebook flight because it was made by another provider. It took hours of communicating with my provider and Emirates staff each of whom said it was the others responsibility. As the time passed, I was eventually told it was too late for rebooking as I needed to do this at least three hours before the flight. Emirates staff also said the would unboard me but I believe I was recorded as a no show. Our first flight from Sydney to Dubai was more cramped than other airlines which was surprising considering their reputation.

Our first flight from Sydney to Dubai was more cramped than other airlines which was surprising considering their reputation.

Bathrooms were amazing and first class seat was very comfortable. Food was edible but not up to the standards of other first class meals on other airlines. But Caviar was amazing! So much caviar. Dom Perignon 2015 was room temperature. It would have been amazing if it was chilled down a bit more. Slippers were amazing and amenity kit requested was beautiful. Requested Pajamas never came so can’t tell you how nice they were. Loved the design of the seat and personal storage. Suite was much smaller than other airline’s first class and tv screen was tiny and remote difficult to use. I probably wouldn’t pay for this flight again.

Had to do shuttle bus both times during the transfer. It was waaay longer than acceptable. These 777s need a refurbishment really badly. Emirates and Dubai Airport used to be top notch. Now overcrowded and outdated.

We boarded but due to a technical issue we spent 4.5hrs on the ground waiting for the issue to be resolved

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.

the seat is quite narrow compared to others. entertainment and food were very good

I had a good experience flying with Emirates. All of the flights were on time staff was very professional and kind. So I had a positive experience..

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

Very pleasant.The crews are very nice.Food were excellent.

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

I have difficulties to book wheelchair for my parents returned flight

Lounge a access was excellent as was the attentiveness and service from the crew as always. The food and drink supplied were of good quality. The entertainment system had a good selection and I liked the mapping system supplied. However the screen wild have been bigger and the operation a little smoother to navigate. The seats were barely comfortable, but adequate.

The usual excellent experience with Singapore Airlines. The airplane was on time and actually early to Haneda Airport. The onboarding experience was pleasant with no delays, perhaps owing to the fact that the flight was not full. Nevertheless, the air crew were their usual outstanding standards in serving the passengers.

Horrendous. We upgraded and they took the money but cancelled one of our tickets. The recline action didn’t work on the seats for the flight from Singapore to London, pre booked meals but they seemed to have disappeared as well.. Phone customer service was horrendous. Took 5 phone calls and no fix. Craig at the airport was the only one who seemed to be able to get the ticket back.

Very good flight from Boarding to landing -efficient and comfortable with decent entertainment options

Excelent service and plenty of food and drinks during the flight. Flight crew very attentive to our needs. Leg room between rows are very disappointing.

The staff on Singapore Airlines was incredible. I would like to commend LS Reuben from my SQ37 flight on November 19th, 2024, from LAX to Singapore, for his outstanding service and care. During the flight, one of my earbuds—brand new and valued at nearly $300—fell out and became lodged in the box controlling the in-flight entertainment system. I was understandably upset, but Reuben went above and beyond to assist me in this tough situation. Reuben demonstrated exceptional determination and empathy. Instead of suggesting we wait for an engineer, he immediately took action, spending almost 30 minutes searching for the earbud. He even got down on the floor to ensure it was recovered. His genuine concern and persistence made all the difference and turned a frustrating situation into one where I felt truly valued as a passenger. Reuben is a shining example of the remarkable service that sets Singapore Airlines apart. His dedication and willingness to go the extra mile left a lasting impression, and I want to sincerely thank him for his kindness and professionalism.

The food options and quality could use some more excitement and variety.

Really enjoyed the flight. Our flight attendant on the way back SIN-LAX was exceptional I didn’t get her name but she was so kind and went above and beyond to make sure I was comfortable. I had a bit of a panic attack and she checked on me a few times to make sure I was ok. Really appreciated her attention and service. Thank u

Overall, very good. The food was better than expected with the exception of the pork and potatoes dinner at the end of the flight. My family all selected that dish and did not set it. I tried a bite also and it was honestly terrible. Also, it would be helpful to know when the snacks in the back of the plane are available.

Seat space was tight and uncomfortable. There was hardly any cushioning giving me a terrible tail bone ache. Getting and out was extremely cramped. We paid for seat choices and felt totally ripped off. Food was mediocre. By the time the servers served 2 or 3 rows they ran out of this or that option as we saw on the inbound trip also. This is infuriating. Entertainment choices were extremely limited for such a long haul. The screen froze on occasion and did not switch off when the on off button was pressed. When it did it came back on its own in 5 seconds. The airlines has gone downhill since last year.

The flight from Abu Dabhi to Bangalore was terrible. The plane was an order model with no onboard entertainment. The beverage selection were very limited.

excellent, the staff was kind and the boarding process was with no issues or hassle

More leg space than other flights, but *maybe* narrower seats

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.

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.

I am a larger than average person and in my opinion i don't think it's fair to allocate a window seat to anyone who is my size or larger, i was seated between 2 large passengers on a full aircraft. The guy in the window seat also occupied a portion of the middle seat (my seat) which made my experience of flying with etihad very cramped and uncomfortable, i was flying from Abu Dhabi to Bangkok. Had this been a airbus 380 it would have been better as the seats are larger but unfortunately it wasn't so i had to endure the 6+hrs unable to get any rest

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.

The check-in has been the very best so far I didn't get to use my priority access which made me feel like a paid a higher price with no benefit for that I loved the food Very tasty and hot The staff friendliness, empathy could be better as it was not linear amongst the whole crew Otherwise, no complaints. I'd still fly again via Etihad Great prices despite the long 6h of waiting time

It was OK as the seat which we paid for doesn’t have any window. We paid $120 for 3 seats but it’s for nothing. Crew could not help. None of the ports worked so all our phones went dry

Surprised that the safety briefing was only conducted in Malay language and no English despite there are foreigners on board. MH should take safety more seriously.

Flights were delayed, Food was good but only 1 meal instead of 2.

Food was good but only 1 meal and 1 pie, instead of 2 meals. Both legs were late.

We are row 11, when the crew came to us, only one meal choice was available.

OK seats comfortable, easy boarding/embarking, excellent connection to domestic Malaysia flight with baggage checked through without customs. Catering especially drinks borderline ok luckily less important aspect

Comfortable seats in economy, managed a few hours sleep in an o night flight but the food was terrible. Surprising as Malaysia airlines has been good in the past. Service was mediocre this time too.

Vast improvement needed in customer service. I couldn’t get the drink of my choice during both meals (i.e. sparking water and Diet Coke). I had used plastic cups falling onto me from the tray. No eye contact when they thank you on the way out signalling an insincere thank you.

Jia yung was the flight attendant that made this a miserable flight.

The flight isn’t great, as the plane has faulty with light and noise. It blinks and make noise for 8hrs non stop! Causing health and sensory issues! Causing Hazard matter to all 3 babies that on bassinet seats. This matters affected 12 passengers and the most horrible flight I ever experience. Have been flying with MAS for more 30yrs and this is the worst! Very disappointed

AC not working, just slowly blowing room temperature air. Long taxi time does not help as well. Sweating all over the whole trip.

Check in was was and the agent was very friendly and helpful The lounge was nice...boarding was straight from the lounge Everything worked at our seats, and video entertainment was good ..food was mediocre

The flight was excellent in World Travellor plus. Well worth the extra money. Boarding at Phoenix was the usual poorly organized event. Very stressful.

Although business class, the seating was really cramped. The food was so so.

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.
