Airline reviews

I had selected seats together for my family of three when I first booked my tickets in February. However, I realized only when I checked in at the airport that the seats I had selected were no longer assigned to us and we were completely scattered across three different middle seats instead of being seated together! After requesting the Singapore staff to have us seated together on a full flight, they managed to find something but it was right next to the rest rooms and the whole journey of 15+ hours was really unpleasant. They said that the seat selection isn't locked and the airline can reallocate the seats anytime. No one ever told us this and it was a terribly unpleasant surprise. Will avoid Kayak/underpricer and Singapore in future

Very concerned with guest comforts going out of their way to accommodate special dietary needs when the guests hadn’t pre-ordered.

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

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.

The food options and quality could use some more excitement and variety.

On time boarding I would like to see ground hostess to help transit customers to direct them to the right terminal and boarding gate. Last night, all the transit customers on SQ484 arriving Singapore had to merry go round to look for terminal and boarding gate to board SQ128 transit to KL Malaysia. We went to Terminal 3 taking the Skytrain to T3 and back to T3 to get out to look for different Skytrain to T2. On arrival t2, we had to go round to ask which boarding gate to KL. We only had 5 minutes to make to the boarding time at 6:55pm but we already spent more than 30 minutes running around to find the boarding gate. We were late at the boarding gate.

Leg room and flight sound insulation is very bad. They broke 3 of my bags with bad handling

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.

People were so nice! Economy seats were small and cramped feeling for me. I’m slender and 6 feet tall

The singapore airline now compared before covid, I like the service before covid. SQ was the best of all airlines but now I am going to look for different airline if I am travelling in asia.

Very attentive crews Flight was very smooth and safe Only little disappointment was the slight delay of departure (~30 minutes ) which rarely happen with CX flights

Not at all satisfactory. I had stomach upsets after taking food. Quality of Asian vegetarian meal was awful. Further there was no snacks/ fruits/ biscuits available as in between snacks.. only peanuts and pitzels.. except courteous staff rest of my experience was far from satisfactory

Staff was very courteous. Plane was clean and quite spacious even in the last rows. Veg food could have been better.

The flight from Hong Kong to Hyderabad didn’t have any power points to charge my mobile. Given we are no longer allowed to use power banks, giving customers the ability to charge even on short flights is critical part of the overall experience.

when i ask for help all the crew members had a look like why are you calling me? very terse and rude.

There were delays at boarding and landing. These events resulted in a tight transfer time in HK. Poor signage for transfers. Finally, lost luggage at final destination.

Horrible airline. Missed my baggage and don’t want to reimburse for the basis items. Pathetic customer service

Bathroom was not cleaned as often as other airlines does. It was gross for a less than full flight capacity.

While I was in great pain, the seat was sufficiently comfortable to allow me to rest and not be in so much pain.

Flight crew was especially thoughtful and attentive, made sure our seats were comfortable so we could rest on the long flight

Entertainment system is okay, flight attendants were ok. Leg space very narrow, I couldn’t get what I wanted to eat, dinner nor breakfast.

Excellent experience with business class area. Staff was attentive and food was amazing. Only one bathroom for business class which was logistically difficult for the staff while preparing meals. Need to offer fluids with meals. I did not get enough water to drink. But overall I rate it 5 star.

As a big guy the seats are way too small for me. Would prefer more comfortable seats on these long haul flights.

The staff at IST airport could have been more helpful. Too much wasted time and the plane from IST to KHI was just horrible. The plane was not clean and smelled bad!

This is my 2nd time with the Turkish airline. Would definitely recommend. In stability we connected to Indiago would not recommend, very cramped seating. No inflight entertainment..service was inferior.

Vegan food tasted good. Restroom could be kept cleaner. Seat tray table was a bit tilted so food tray kept sliding down a bit. Flight crew can be a little more friendly, caring and approachable. Their faces lacked smiles and tone was stern.

Flight was delayed then we had to redirect for medical emergency during which time we had no information on what is the plan. The connecting flight was also delayed.

Awful seats, poor air circulation. Smelled like poop for 3-5 mins after someone used the bathroom. Child screaming for 13 hours

We are thankful for the useful gifts provided by the airline.The entertainment and crew were also very good

Quality of service on board was very inconsistent. FA service primarily seemed robotic and they barely engaged with passengers

The flight was smooth Thank God but the delays and changing gates for 3-4 times made me so tired of walking back and forth with heavy bags I thought I was going to pass out with heavy headaches but Thank God finally found the final gate and home safe. These delays happen anytime for important reasons so just be patient when you come across these situations.

Delayed my flights and no communication. We end up spending 6 hrs in Doha. No food or any concern from the airline. Terrible

Between Air India and Qatar my luggage was lost for three days. I eventually found my own luggage location using the Apple Air Tag. Air India used a paper form to report my lost luggage. I could never get past getting past luggage personnel with my report number before they would hang up on me. Only after them specifically telling Air India at Chandigarh airport where my luggage was located which was right under their noses did they react. After three days I finally received my luggage. The Air India luggage folks didn’t seem proactive in finding the luggage’s rightful owner.

The made us waiting and held our passports and boarding pass making us miss our flights

Wore experience due to delay and took me 3 days to reach my destination.

The overall experience for the price we paid was mediocre. Nothing outstanding! Check in process was standard. Flight attendants could have been more well mannered. I found it rude when the attendant nudged me with the snack box to grab my attention when not looking. She could have said ,’excuse me’ instead. My son’s in flight entertainment was not working. The food was not great either. The snack options were not so great with kids in mind. Overall, might not travel qatar again.

Crew members service are at its best Seating area is very compact, could be better

Boarding was delayed by 2 hours since the machine that assigned boarding passes broke down and we were left waiting to drop our luggage

Excellent service and very comfortable business class for a long journey. Carry on bags in business class weight limits

The boarding was very unorganized, they had my dad “83 years old “ stand for long time to Wait in the line then stand behind the counter, we had two kids with us but the separated my dad from us for long time

Food was below par Quality and None of the Entertainment systems were Working ..and we were unable to turn it off.. Due to the glare we couldn't even sleep for the entire duration of the flight ..

Several seats in business class were broken. Some would not recline, others had other problems. They need to really update the seats and AV.

Never can get flight and nof light for three days .finally travel by bus. Very bad experience.

First and the foremost I was shocked to see airindia standards have come down so low . The food was horrible . They served us 3 meals for vegetarian and all the was paneer . The orange juice was not at all cold it was smelly . After you take this heavy price air India should learn from other air lines . I at one point felt like throwing up . After all this when we landed we were not given landing slip . We had to wait for 45 min at the immigration just because no one was given landing slip . To top it all we were 3 passengers and had checked in 4 check in luggage . Out of which 3 have not yet arrived . Basically status says the loaded it in our flight ( this was a direct fight ) and it never reached . We are still waiting . There is nothing great to tell about our flight . The he only good thing was the crew were very helpful .

Lay out shows 1st row and second row given after taking payment. It's a fraud

Very old plane. Broken tray tables n seats. Entertainment system super slow to operate and very little content.

Screen are not working. Windows not clean. Staff is very good. Food is okay. Experience is good. I hope the up coming is more then betters for others airlines thank you.

This time I felt better. Air hostlers. Need more and more improvement on transit. Get more trouble and painful with service.

Lot of things AIR INDIA needs to improve. Poor service for wheelchair. Crew has improved after TATA took over, yet there are some crew who are still live in old mindset . Throughout the journey we have faced number of issues. For example , my wife boarding pas was issued in some other passenger's name which put us in problem. When AIR INDIA at San Franscisco later issued correct boarding pass, they did not change tag on checked in bag with correct name, This led to hold on of our checked bag. They moved us here and there to get our bag. Food was dried.eg. Rice plate was hot but it rice were dried. Once, I was not given my food even upto all completed their dish. It was given after reminders and when I got later some items were missing. Wheelchair service is poor. The wheelchair carriers ask money at every stage, not only that but they demand more money. How can they ask money from old, aged citizens and disabled persons. This is absolutely nonsense. Even I did not get my checked in bag at Vadodara Airport, it is still missing. They have not given me copy of complaint, only they registered complaint. I also got my one checked bag in damaged condition. There are different issues at different locations which I do not want to highlight. So overall service is poor.

Food was ok. Crew were good. Tv and outlets weren't working at all so nothing to watch and no way to charge devices on a 17 1/2 hr flight. That was not great. Bathrooms were dirty and smelled terrible. Also my multi tool was stolen out of my checked suitcase.
