Crew and service excellent. 2 hour delay for takeoff. SQ app showed flight on time.

Headwind delayed our flight which wasn’t the airlines fault

The food wasn’t good at all. I skipped meals .

We were not given option for meals since they ran out of the other option but good thing the remaining options tasted great.

Both the staff at check-in counter and on board were pleasant and helpful. My chicken and mashed potato was good, sauce was tasty, but the zucchini, carrot n other accompanying vegetables were over-cooked a little. (I understand the meal has to be prepared earlier). Yet I would fly on Singapore Airlines again and recommend it to family and friends.

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.

The seat in economy class and legroom in Singapore airline are narrower than Korean airlines! I don’t have that comforting feeling flying with Singapore air as in the past!

Loved the airline with the exception of their carry on limitations. They enforce a strict 7 kilo limit for carry on baggage which is ridiculous. We traveled from SFO to SIN with carry on with no difficulty yet when we checked in Delhi they forced us to check the carry on bags. The weight of our carry on bags were 11 and 12 kilos and while they exceeded the limitations set by Singapore Airlines they were well under weight limitations set by may other carriers. Interestingly my wife and I were each allowed two 22 KG bags to check in addition to the 7 kg carry on for a total weight of 102 KG's. Our total weight with the one bag we planned to check and our two carry ons was 46 kgs.

Crew and service was excellent, but passengers should be offered a welcome drink before take off which did not happen. Food was very good. Unfortunately the lie-flat bed in business class was one of the most uncomfortable I have experienced. The configuration forces you to sleep with your legs at an angle instead of in a straight line, plus there is very little padding on the bed so it wasn't possible to sleep for more than 2-3 hours on an 18 hour flight. For what the airlines charges for a business class ticket their hard product leaves a lot to be desired.

Food could have been better. Too many passengers getting up and down all the time.

The food was great and the service and attitude was amazing!!

It was a great experience. The only thing I would have changed was that the bathrooms were never cleaned and they got very dirty.

Old airplanes small seats expensive tickets, not as expected overall and not comfortable according to the price

It was an OK flight with below mediocre service by their flight attendants

Wasted a lot of time trying to find the CDG lounge - it was not next to the connecting flight gate like the Air France staff said.

My experience was good overall, the quality of the food really decreased! There used to be a choice between meat and fish now it’s between chicken and pasta! In the choices of entertainment meditation has been added which is very good. Soft chair workout to improve blood circulation and avoid phlebitis should be added.

The only reason the overall rating wasn't "excellent" was due to problems in claiming luggage. The bags are delivered to the main area (Cinta 35) for domestic passengers, but to a DIFFERENT ROOM for international arrivees. After waiting 30 minutes, someone (who didn't appear to be from Air France or the airport) told us to go to another area. There we found our bags, which appeared to have been awaiting us for a while. We had to go through a bag check before leaving the airport. If we had been alerted to this possibility, or better yet, been to go directly to Cinta 34, we could have eliminated quite a bit of waiting.

Much better than the major US Carriers especially in Biz Class.

I wish that the meal included a vegetable or even a salad instead of couscous! Why serve chicken with rice AND couscous? Service was good overall though a bit lacking in friendliness. Usually on air france I've been offered a glass of champagne before dinner, wine with dinner, and a digestif after dinner. We were only offered wine this time!

It was not Air France but Air Europa. But confusion over our checked luggage. Whether it was checked all the way to Tenerife or not. It was not. Had to line up again in Departures. At least our Sky Priority was honoured. Flight was fine.

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.

From the start of the check-in process, the associate was unprofessional and claimed that my ticket was incorrect, attributing the issue to Gulf Air. However, they failed to provide any clear explanation of what was wrong. After an extended wait of 45 minutes, the issue was resolved, and we were finally issued our boarding passes. Upon arrival in Paris, we faced further delays as the stairs to deplane were not functioning, resulting in an additional 45-minute wait onboard. This delay posed a significant risk of missing my connecting flight.

Had to discuss more than 15 min regarding wheelchair they gave only at the start location. No food serv in 1 st flight. Considering flight started at 10:00 pm so had to starve for dinner. Checkin screw was polite. Food in 2 nd and 3 rd flights was not good. It was too cold in the flights. Had to ask for blankets. Missed quality all thru, though the fare was on higher side

Food could have been better Entertainment was absent even in Business Class

I like it very much. Gulf Air is always the topper rank of the world. I love it very much.

The drinks should come before food. Unable to have any fluid unless after food. Thanks

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

Great experience. Flight was on time and reached destination on time

Boarding and flight update was fantastic as I experienced about a 10-15 delayed for both flights. The food served onboard was great; the service of the flight attendants was excellent.

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

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.

The service was really good. The breakfast food could’ve been better as I don’t eat sweets for breakfast and the only choice was a muffin. Overall, good experience though. Thank you.

Not what I expected for the last leg of a $5100 business class experience. Boarding was a nightmare. The flight was delayed and I had to keep checking my email to ensure I was at the right gate since the airline or the terminal had no clue until 15 mins prior to boarding. Food was gross, limited drink options.

Flights scheduled with impossible connections - Lufthansa apparently believes it takes 7mins to change terminals, go through passport control, re-clear security and walk 1.8kms…..and everything will work perfectly (which it never does at Frankfurt). No staff on hand to assist with transfers on delayed flights. No transfer guidance provided by app. No compensation offered for 6hr delay to connecting flight.

The only thing that the airport can improve which will help Lufthansa from delay flights is to warn the passengers that are flying to the USA to be earlier to the gate due to the documents check that in our case delayed the flight

Crew were friendly and very helpful Plane was clean and the legroom is standard. Overall a good flight, no complaints.

Everything about the flight check-in was smooth no line the plane is clean and bathroom

Excellent everywhere but Philly, the most rotten airport in the world.

Check in was not the greatest as had to talk to an agent to clarify things and then he transferred us to another agent who had difficulty processing my credit card as there was a system glitch and not a card error.

All good. Loo’s weren’t great and as clean as i would like.

A great flight. The crew was excellent too. Of particular note of excellence was the gluten-free meal which was one of the best offerings I’ve ever had on a plane. Outstanding work, BA chefs.

I was put into business class. Wow! My flight attendant was great! The food amazing’

I got stuffed on both flights into terrible seats. Second flight the seat didn’t even recline and fit s tall person, that’s very uncomfortable.

I arrived at Bridgetown only to fins that a suitcase was missing. It was left at Manchester. I had to wait wait 2 days before deciding on going to collect from the airport personally. I am not happy about paying for baggage at the airport. This I thought was included in the price of the ticket. Who goes away for 2 weeks and does not bring luggage. This was a total rip off and I am not happy. I need someone to contact me before returning so that I don't have to pay all over again to return homde.

Boarding market okay just because of the delay we had, but not related to the crew in any way…

Not so good with their baggage handling as they damaged one of my check in luggage
