There is an issue with A380 when it arrives in Munich, because a business class passengers like me have to wait for the first class passengers to disembark, which takes some time while you are also offloading economy passengers this causes an issue at customs where your business class passengers end up behind a large bulk of economy passengers This is a frustration and the early dislocation should be and is supposed to be a benefit of business class

Great flight - Clubhouse met our needs, and the staff provided good service. Boarding felt a little chaotic, but given the size of the aircraft, it's always going to be challenging. Whilst the crew were friendly, the number of passengers meant that we received our breakfast items, but had finished breakfast before we were served a drink. Lunch was much better organised, and throughout the flight, the crew were attentive. Found the seats and ICE to be excellent. Disembarkation was fine, and everything possible to expedite the process was being done.

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

I take emirates because of direct flights Otherwise no Cabin crew niot friendly and never friendly across the airlines Planes old inside not renewd .. this is not an issue The issue is the poor service

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.

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

Can’t complain Only downside was the Kiosk passport check and customs clearance at Melbourne. When will they improve that service🤔

Similar to Hyd->Dubai this too was worst airlines. Bad seats, bad seating arrangement which created lot of confusion since family member were not given seat together. However most of them changed the seat and got with the family. Cheap tactics by Emirates.

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

Flight was delayed by and hour but were informed beforehand

I find it was a bit hot before take off. If there is a way to improve the airflow it would be great

Excellent service. I pre-ordered gluten intolerant meal and they handle it with care. They served me my meal before other people's to avoid crossed contamination. Thank you 🙏

No frills airline with minimal leg room and no entertainment

The flight arrived on time. 2×2 seating meant no one needed to sit in the middle. This was a connectibf flight from Singapore and required going to 3 counters in different levels to check a golf bag

Food was just okay, need to improve for other menu variations

The consistency with Singapore Airlines is fantastic. Crew are always brilliant and food delicious in business class

Wish the seat don’t have restrictions, can’t fully insert backpack all the way inside.

Service was top notch and the attention to passengers is great. Takeoff and landing was on schedule. Food selection is good

I have difficulties to book wheelchair for my parents returned flight

I was in a middle seat where I felt a bit too cramped otherwise the trip was good

Couldn't access entertainment on app as said in an email

Excellent as always, I won't fly to Australia, and back to the US on any other airline. The flight crew is always top notch, and have a way to make one feel extra special. Thank you for your service, I would rate Qantas Airways a 10+.

No internet on flight, which makes log travels really hard.

they ran out of fruit for breakfast and so I just had a yogurt instead. other than that the flight was good

One of the best Qantas business flights I've had. Quality product

Great as usual, some delays but well communicated and made up for in the air

We were upgraded and after just a short delay in attending to a safety check we were on our way. Would definately fly Qantas International on their Dreamliner again.

Five hour flight instead of four hours due to westerly headwinds which wasn’t the fault of Qantas !

I tried to check in online but was unable to do so. I stood in line for nearly two hours to check in. American Airlines was understaffed. When I finally got to the kiosk to check in, I was still unable to check in. No AA staff was available to help. Finally one of the airport security agents who was helping passengers became of lack of AA Staff told me: “I think the reason you can’t check in is that you are starting your name with an upper case letter when you write it. Just write it with all lower case letters.” That did allow me to check in. HOW COULD ANYONE POSSIBLY KNOW THAT IF THEY USE AN INITIAL UPPER CASE LETTER TO SPELL THEIR OWN NAME, AA WOULD NOT ALLOW THEM TO CHECK IN?????? Then I had to wait in line over half an hour again to drop off my baggage. Although I arrived at the airport 3 hours early, by the time I got to the gate, they had already started boarding.

The wifi was out. Otherwise it was great flight. Richard, as CSM, was excellent.

Staff is rude and condescending. Airline is badly managed. They take away their flimsy earphones and blankets one hour before the lading. I’ve never experienced this with any other airline. It’s a very portly managed and run airline that should be avoided.

The Senior Flight attendant was just amazing on our Flight GF 284 on 30/11/25. She was so attentive, helpful and caring not just to us but to all in our cabin.

Loading was on time and quick Not very many people

Amazing business class in a single aisle plane. Fully flat seats, pyjamas, amenity kits, all in all a really complete product. Service was good - not amazing - but they did a good job. Got a few hours sleep. Will fly with them again if I can.

They flight was without ait conetion weather was very hot

Did not have to leave plane. However found the wait tiring with nearly a full plane boarding at Male and being unable to get out of seat due to cleaners security and a full plane boarding with hand luggage. Staff were excellent despite a long and tiring flight due to stopover.

Everything about our return trip from Colombo to Manchester was excellent. Staff were brilliant all flights. Return flights on time and all staff were brilliant. The outbound journey however was marred by cancellation of Man to Bahrain flight. No information or staff assistance. Customer Service none existent. Told to make own arrangements by none interested or understanding telephone staff who said to make own hotel arrangements and be reimbursed. CS refused to reimburse hotel or lost lounge booking or taxi fees.

The boarding was late. The check-in board said boarding closed but the boarding hadn't even started. I have spine issue but not eligible for wheelchair since I can walk. But we were taken to a plane with stairs to climb. I requested support with the handcarry and was told that I shouldn't have booked this flight without wheelchair. Instead this information should be public if this plane has sky bridge or stairs. The infotainment system did not work either. And the plane was very loud with very less legroom in economy.

Very poor experience, passengers and were not social and started a troubled with other passengers and a fight erupted

Worst flight ever.service was extremely poor and food taste was horrible.Served me mashed potatoes and chicken calling it Briyani.

The space in the seat was okay, the staff were friendly, the entertainment system, my touch screen was not working and some of the films listed on the website for the flight were not available.

BA flight from London NY had old BC configuration with 2+3+2 seating with open seats which was not comfortable and lacked privacy

Flew business- but plane was dirty, food horrendous. Too many business class seats diluted service levels overall.

Loved the boarding option from Business class lounge, experience on flight was excellent, plenty of good food choices

I don’t think you’ll like the shoulder require people to pay to reserve seats. Also for the people in the bulkhead row the luggage locker nearest to their seats should be vacant. Both sides were filled with crew or airport items.

Experience was bad. In business class, they ran out of food choices. Luggage was delayed by 2 days in both to and fro flights, ground staff was not helpful, took 3 hours to log the complaint for missing luggage.

We got delayed for 3 hours and. Missed the connection. This is the 3rd time this happened with this airline

5 hour flight with no food or on-board entertainment. Flight crew barely made rounds to provide water.

Staff except one has poor attitude. No cabin crew seen for several hours during the flight in business class. It felt like I was traveling in economy Drinks bad in business class Flight was late for no obvious reasen and I missed my flight to Miami I was put in a 3 star hotel in London although I was traveling in business class. Dinner was aweful at the hotel Overall very poor experience

The transit at Heathrow was an absolute and total nightmare. Absolutely gut wrenchingly horrible and scary. Embarrassing that their National air carrier cannot figure a half decent experience for passengers to transit via London. Shameful.
