Overall were very good and I was satisfied w/ all the food and services.

Service was very good, food and entertainment systems were good

Food was served to different people at different times and it wasn't clear why. The crew apologized for the wait. But it felt odd and inconsistent. They could use charging ports on each of the seats. Mine didn't have any. Also, they could've offered more snacks. It was a 12+ hour flight and no snacks were ever offered. Everything else was OK.

I wish there was a little more leg room between the seats. The recline was good and seats overall were comfortable. I also didn’t like the 2-4-2 configuration.

toilets could be cleaned more frequently, everything else was pretty good.

The crew was very courteous and professional. the flight is relatively clean and comfortable.

Pleasant business class flight experience with good onboarding experience. Flight service team was excellent with usual book-the-chef menu available

a completely full flight - felt quite carmped in, despite being on the window seat. Meal served could better. Surely different from pre-covid trips I used to take to and from Bangkok.

SQ service is great as always. However, the food quality seems to have gotten a lot worse recently.

Wish the underseat compartment don’t have a restriction, can fit a personal item such as backpack fully like most Boeing

Dirty and smelly lavatory and toilets in Wamos Air operated flights

Good flight. There were a few issues with the flat bed. It was some technical issues. Otherwise everything was good

Was so disappointing. Business class with no TV, uncomfortable seats. Had much higher expectations.

Etihad Check In counter/Station manager in Heathrow was bothering and not helpful at all. They are rude and not customer oriented

It was an old plane with seats not comfortable and with little space for the legs. I must say that the previous flight I had was amazing on a very comfortable new plane

It’s a business class ticket but they didn’t give a lounge access

1 hour flight. No complaints. Some drinks would have been nice.

Crew was amazing as usual. Very comfortable for a 13hour flight. Check in at ATL was terrible. Ticket counter charged me $200 for a small bag. Apparently Kayak sold me a zero luggage ticket. No carry on no checked. So the check in desk charged me a bullshit $200 dollar fee for a small gym bag weighing less than 20lbs. In true 3rd party ticket buying. This will turn into a finger pointing process between Kayak and Etihad. Now I'm going to have to ship my bag back in the mail a day ahead of my return flight.

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

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

Pretty much what you'd expect for an economy flight. The crew were excellent as usual. The food was ok, but nothing special.

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

I was asked at the gate to put my carry-on luggage into the metal size-checking unit and it scratched my luggage. I suggest lining it with a cloth to prevent damage to passengers’ luggage.

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!

The flight from Dulles to Munich was just okay. The seats were comfortable and extra foot room was noticeable in comfort plus. Disappointed in the booking in so much I requested an aisle seat and then was assigned a middle seat. The food was inedible. Movie choices were moderate. I usually fly Delta, but this WA flight was cheaper. Next time, I'll happily pay the extra to fly Delta.

Staff was very professional friendly food was okay i used the lufthansa app and it was great told me immediately what gate I should go i would fly with lufthansa anytime

The flight crew was friendly and accommodating. I witnessed one of the flight attendants deal with a difficult flyer with extreme calm and compassion. I was so annoyed with the passenger and so impressed by the flight attendant. His quick action de-escalated what could have been a major incident. He was awesome.

The pasta in the evening meal was tasteless. Otherwise, the flight was okay.

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

Flights were delayed but very last minute, also seats felt very squished on the second flight. Crew was very friendly and airplane was clean.

I darted through the Frankfurt airport to make my connecting flight. I asked if it was a possibility to upgrade and the agent did. This was the kindest gesture and it made up for the previous delayed flight and distress/anxiety of anticipating that Zi was going to miss my Frankfurt-Chicago connection. I cannot express my gratitude for the upgrade.. I am 5feet 10 inches do the leg space was amazing.

I was unable to board this flight because of visa changes that I was not alerted about and I’ve been unable to contact Kayak to obtain a refund / credit anything.

My touch screen at my seat wasn't working, the films BA advertised on the website for this flight were not available, and the plane was a little dated, food was good and the staff were good, just let down by the aircraft facilities.

Did not like the seating configuration at all with 2+3+2 in business class. Lacking total privacy and comfort

Check-in experience, for business call please provide a premium experience

Lost my luggage, ran out of food choices in business class, ground crew was completely unapologetic.

Excellent. The crew and flight were great. Checking in was easy and everyone was very helpful.

Late. And service was very slow - passengers sat for well over an hour with dirty trays etc surrounding them

Entertainment devices on A380 need to be fixed, the seats might do with updates.

I like everything about British Airways. Excellence. Perfect. Exquisite service.

The plane was dirty the food was awful and the boarding process took too long
