Airline reviews

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.

Delayed 1hour due to storm still didn't get window seat for third flight despite paying £240 extra to book them

Everything was great keep up the good work 😁, can't ask for more.

Flight from SFO did not include entertainment as it was not working the entire duration of the flight. Was informed that there would be a $350 voucher for the inconvenience. Uncertain how the voucher will be provided.

It was an average flight. I would have expected more from this airline. Food, seats, service, etc was just average. I just give them some extra points for offering free WiFi on board with just a Krisflyer account.

Check in was easy through self-check-in kiosks just like domestic flights. Staff onboard were fantastic. Some "book the cook" good options weren't great, others really good. Entertainment options a bit limited to what I've experienced on Qantas. Overall a good flight though, especially for the price.

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

We are glinting with united , but over all very disappointed

We are flying with Swiss for a long time but this time was terrible do to are flight cancellations we are in some bad hotel with out normal food

The plane was good - on time! But can the stewardesses smile or actually be nice - not to bark the commands

This time, I traveled in the economy, and it was surprisingly better than the eco-premium (food, comfort, and crew were noticeably worse in premium!)

Edelweiss is now Nickle&dimming, not even a complimentary wine on the intercontinental flight. Sitting space is the smallest I have ever seen.

Lots of water brought around by staff which is very important to stay hydrated on a long flight. There provided swiss chocolate icecream! The attention to detail is obvious. They really want to make their passengers entertained and comfortable.

Flight was cancelled due to technical problems with the aircraft. It would be nice if SWISS would invest in new aircraft; that would for sure minimize the technical issues with (old) aircrafts.

overall the flight was good and we were happy they waited for us. However, our luggage didn t make it and this caused us a lot of problems.

Excellent Airline. Food, crew and comfort was perfect. Entertainment screens were old. Didn’t like them.

The seats had no space at all beyond the knees. The seat in-front literally reclined on your face, very uncomfortable plane. Was nothing like the normal SWISS experience. The food was okay but could be better.

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

Gulfair were on top form and everything went as planned

The entertainment on board was really poor. The map doesn’t give enough information and the movies have arabic subtitles, you can’t choose. The stuff wasn’t very friendly and the breakfast really poor. The food must not be spicy! They didn’t have enough drinks.

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.

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.

It was my first experience in business class. It was everything I expected and more. Service was impeccable, food was delicious and I felt rested once I arrived to London

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.

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

Zero legroom or space in economy. Flight was delayed into Munich causing a missed connecting flight and other missed bookings. :(

Everything was fine except the landing. We were off loaded on the tarmac. Squished on busses then driven around for 20 minutes. Dropped at terminal B and needed to be at A so had to wait 20 min in another line to catch a bus then another 20 min wait in customs! How on earth were we to get to our connecting flights!? Not a great first trip with your airline or start of my vacation. The woman on the tarmac was rude too

Lufthansa crew are great Frankfurt to Raleigh RDU North Carolina USA

The connection to LYON was very tight. The flight was nearly finished boarding when we got to the gate

Terrible. Super uncomfortable/less room than a domestic flight and flight was 9.5 hours. Food was terrible. Flight attendants slammed the cart into 2 people in our party numerous times as they were both over 6' tall and sitting in the aisle.

American Airlines seemed to run a 'dry' flight. No alcohol was offered at any point with meals. Breakfast was a bit tasteless. The 'hot pocket' whatever that is, was horrid breadish pastry with very little filling. Decaf coffee was horrid. Seats didn't seem as wide or spacious as usual, especually for a ten hour flight.

We found the bag drop/ check-in proceedure at T5 unnecessarily complicated. We paid extra for seat selection in advance and were allocated worse seats at T5. We found the check-in person was not particularly helpful although the the staff at the gate were super good.

Very dated plane. Seat was firm and uncomfortable. Entertainment system almost laughably outdated. Poor audio. Picture was always too dark.

The seats on the plane and at Heathrow Airport are so uncomfortable

They did not provide free WiFi, It could be purchased for, I think, around $25, This seemed excessive.

Good flight, awful, vindictive, vile customer services in T5 Heathrow.

Ok we did get an upgrade and the flight was delayed 45 minutes BUT without any bias. The crew were excellent, friendly, efficient and verging on exuberant, they all were so happy to do their jobs. Food excellent and the new safety video is fun to watch.

Reliable, great value, but not outstanding in any aspect. This is similar to the experience you get in most international carriers like Etihad or Delta.

Aer Lingus was the actual airline so they handled everything professionally.

Flight got diverted because of an emergency and the crew were fantastic and probably saved that passenger’s life. While in emergency landing some measures could have been taken to prevent additional delays. In general not great experience with BA. I used to fly BA years ago all the time, very disappointed by the whole experience, seats were tight, bathrooms tight.
