Airline reviews

I had the worst experience of my life in travel. Due to circumstances beyond my control (catastrophic traffic accidents on the highway between Gold Coast and Brisbane) I missed my flight for the first time ever. Because I booked through Kayak Singapore Airlines were not interested in helping me. They told me to contact the agent that I booked through. I was extremely stressed as I had connecting flights in Europe. First Kayak told me that the next available flights were in four days time. Then they told me that they could do it but at a cost of $2600 AUD. When I agreed he told me that he was having trouble getting it through Singapore’s system and he would contact me further once it had been done. When I had not heard from him after several hours, I phoned Kayak again, spoke to a different person who said he could do it for $8200. I declined and told him to cancel the booking. The worst part of this experience was that I had booked 5 flights altogether with Singapore including Premium Economy on two legs and Singapore cancelled all my flights including the return legs leaving me with having to completely reschedule my entire trip. Kayak refunded me $2000 from $5200, obviously leaving me out of pocket. This has left me feeling that I will never deal with Kayak or Singapore Airlines again.

Clean modern comfortable. Food could have been better, I only ate breakfast I wish they wouldn’t wake sleeping passengers who would rather sleep through dinner. No tea or coffee for breakfast

Kayak really screwed up by offloading the booking to a third party. They were completely inept and caused a bunch of toil. I will never use Kayak again.

I had ordered vegetarian food. What I was presented was extremely dissatisfying and not up to the mark. I pretty much did not eat entire 19 hours. For.an airline voted as best in business, it was extremely disappointing. Seats were not comfortable to sleep. Entertainment system didn’t have much choice. WiFi didn’t work for more than half the time. Cabin crew were also difficult to understand. A bit of diversity like Emirates crew would go a long way.

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

We flew business class. It was excellent. For a 6’4” individual, the seats were slightly uncomfortable for sleeping. But this is only comparison to other business class seats. Otherwise, the crew was incredibly attentive, And the service was impeccable.

The booking experience was bad. Our six character booking ID number disappeared the day before the flight, We could not find out what happened or what was the status of our flight, scheduled for the next day. We finally found the right number to contact Singapore Airlines on the matter (not easy). The Singapore agent worked through the issue in a little over thirty minutes on the phone, the day before the flight. That was great. I'm very happy with Singapore Airlines and their performance. Contact with a competent person on the matter was near impossible. It seems no one in business these days wants to deal with customers once they've pocketed the money. There were resellers, including Kayak, involved in the chain. When we finally got through to Underpricer, we did get a return call that could have proved helpful. But by that time the matter had been resolved by the Singapore agent. Majestic Vacations, the reseller who received the payment was less than worthless. That's just a fast buck operation. Ugh.

Good flight. The food was served a bit late, hence a hurry to finish before landing. Excellent crew and service

I commend the flight attendants on our SFO-SIN flight who went above and beyond to provide us with extra snacks and food. This type of service makes the flight experience personal and awesome.

They are great with every aspect of customer service. Helped my elderly father and aided him with using the restroom.

Very bad service and food variety will never come back again

My baby was with me it was really good experience with emirates

Fantastic as ever. Great staff super catering and excellent service.

Flight and entertainment great. Food needs to be improved, only one choice on the menu. Staff worked well throughout.

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

Everything was superb, only bad point was that the fast track on London Heathrow arrivals was not handed out to me and I had to go back to the gate to collect it.

Superb experience. I hope they bring back the fast track option at Heathrow immigration.

I liked theAVML food. Taste was alright and quantity was enough. Sometimes during the flight I felt that the smell from toilet was coming to the cabin

You can improve in many ways First the crew in general is good, but needs to work with passion to their works not like robots Second, collecting the ear headphones long time before landing is strange The crew should deal with the passengers with respect and descent way not like giving orders

Maybe some more information as to why the flight got delayed I understand may be tell your customers that missiles were fired at a specific airport wouldn't be reassuring to the customers and would cause mayhem but something like recent events have cause a delay on your flight or smth

They lost the baggage and said it was deleted from the system. I had baggage tag so was able to file the complaint but there was no PIR number and update so far

On this flight...fine. The one from India to Abu Dahbi, awful.

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

Stewardess was attentive and was actively roamin to check the passengers on the biz class

This flight was a dreamliner so I think the space was ok for the legs, but the option for food was again limited and the crew was same.

I did not have a good experience in both flights of Etihad. First of all, when I was booking the flight, there were two options. The first option was a cheaper flight with longer layover (9 hrs), or a more expensive flight with shorter layover (2 hrs). I booked the expensive flight with shorter layover because I wanted a more comfortable trip. A few days before the trip, Etihad informed me that the departure time of my first flight will change 7 hours earlier, leading to an 9 hour layover, without giving me another option nor reimbursing me for the extra cost. They didn’t even send me an apologetic email for this change. Regarding the flight experience, I would rate it as mediocre. This is mostly because the pilots of both flights did their best to give us the worst approach to airports that I have ever experienced. In the case of the first flight they had to aboard the landing and took off again right before touching the landing strip. The captain said that it was due to wind conditions but the second time the pilot followed the same direction as the first time to land the plane.

Ripped off and broken seats in Business class. Seats stink and need to request the staff for additional bedsheets. Crew if very friendly though

I request kosha food all my flight but this flight didn’t imclude my kosha meal.

Entertaiment center needed on that flight. I dont like to use my phone for entertainment.

Comfortable seats, good service overall. The food could’ve been a little bit better. The boarding process was slightly chaotic and in fairness, not all of that is related to the performance of British Airways.

The chairs were a bit tight even though I had extra feet space…2nd plane didn’t have entertainment and even though they said there was free WiFi-I believe the free WiFi wasn’t accessible unless u had some account set up….which I didn’t figure out

On time. Comfortable sats. Clean aircraft. Friendly crew. Good food.

Naples airport not the best ! Boarding via coach to aircraft never the best. Staff and captains announcements good. Flight on time with soft landing. Ran out of sandwiches half way down the plane. !! Not impressed. 7/10 satisfaction overall

The seats are not comfortable if you are not tall.

The flight was cancelled and I was re-routed via an inconvenient routing proposed.

Overall great! They could add more entertainment option. They kept running out of vegetarian food options and I got travel packs. This happened on all legs of the flight. Need to plan for it better - I am sure you have some data analytics from all your travels.

Better service to offer drinks in the middle of the trip

They can improve Everything, a 12 hour flight has just 2 meals and the meals are 7 hours apart, wtf are they thinking. At the very least they should have 2 refreshments like some small snacks with some water or some other refreshments since there are people travelling with medical conditions. The services and seats were genuinely horrible

As I remember my last BA flight - mediocre at best. Uncomfortable with poor and minimal food and drinks. Screen broke shortly into flight so didn’t have access to entertainment either.
