Very good crew, very efficient. Unfortunately not all items listed in duty free catalog were available.

Many changes need to be addressed from airport check in to flight departure. If they observe other major airlines, then they can expect what Sri Lankan airlines need to update their procedures.

Very professional and well managed. On time, great staff and comfortable.

Smooth takeoff and landing. Best service experience in all our travels over the years. Caring and attentive crew. Loved our flight to and fro.

not looking like a national flag carrier.. both the ground team and flight team are far from being kind and helpful. Not sure what's wrong.

Kayak company fake total I m not travel my payment reverse plzzz my credit card

I m not good serves poor serves I m m fake company kayak ok plzz my help my ticket cancel my tripe ok

Terrible experience. Unexpected wait due to staff delay was not taken proper care. Food inflight could be better where as flight attendees on flight hospitality was 100%

Aircraft used fir this route was pretty old. Seats 💺 were hard & difficult to reclaim although it was flat bed

Because of the bubble agreement b/w India and Srilanka, I was not allowed to board the flight to Columbo. My experience about airport representatives was good. They were through in their job and saved my family from getting stuck in Columbo (as I would not be able to fly to Doha because of bubble agreement). So by their prompt attention, such a catastrophe was avoided. For this reason, even without flying with them, I would rate them 7/10.

Communication was terrible. Flight was delayed for 4-5 hours in DC (on the front end, and also after we boarded, we had to get off - some issue with fueling the old plane correctly). There was little to no information on timing or what was happening. Once we reach Delhi airspace, apparently there was weather that caused us not to land - we were actually near the ground, saw the run way, and lifted back up to the sky after being sooo close. Then we circled for about 30 minutes, and they decided to go to Jaipur to land until the weather cleared and to refuel. Again, once we landed in Jaipur (wrong city), there was little to no information on timing or what was happening. Then we heard that the crew was reaching their 24 hours. We sat on the place, on the tarmac for another 3 HOURS, with no food and not enough water for everyone on the flight. Then, they kicked us off the plane with no plan, in the wrong city. We went thru customs, got our bags (thank goodness), and had to ask a bunch of staff what was happening and what to do. Eventually, their soltuion was to bus people back to Delhi (like 6 hours we were told) but not everyone would fit on the bus, and unknown timing on when it would leave. At this point it was 9PM (we were scheduled to arrive in Delhi at 11AM...). My husband and I decided to risk it and take a cab that we had to pay ourselves (about $200 US dollars) to get to Delhi (about 5 hour drive). We both had terrible trips back to the US as well - almost missed connecting flight, forced to pay for carry-on luggage (a small back pack!) and duty-free goods by the Air India staff last minute. Just terrible experience all around. Never again with AI! The ONLY good thing was the air hostesses were kind and patient - example: they made sure people with food allergies got their correct. However, the TV's in our entire row did not work so I'm glad we brought our own entertainment......

Their security process is excessive. We were checked when we got off our incoming plane, at the gate and up the stairs when boarding the plane. Come on.

Mediocre staff, crappy food selections and no entertainment for a 14 hour flight. The only good thing was that it was a direct flight.

Interment is zero tv wasn’t work phone charger plug doesn’t work moves doesn’t work

Very very impressed with the proactive care and alertness with which ABHISHEK Chowdhary took care of us. Quietl,dignified , very alert, and meticulous. Very impressed. Also with SUNiL Kumar who was there for us in a very helpful way. SHERLY ALEX On Flight 119, BOM TO JFK CUSTOMER ON SEAT 21C, 21ST March 2024

Bathrooms were horrible. No cleaning and floor was full of tissues. Understand that passengers responsibility to keep it clean but crew should check if tissues are there or not. Also, they announced that baggage will be at one carousel but came to a different one.

The crew smile nicely when you board and exit, in between they are sullen and innattentive

No first drink available for 10 hours so make it easy for beer or wine

I liked the timing but rest all were bad like below: 1. No restroom and food in waiting area at gate before boarding the flight. There was 2nd security scan at gate C2 and if someone goes to restroom which was outside that gate have to again go through security. So not having restroom, water in waiting area I felt is a blunder. 2. Entertainment system was not working for many passengers including mine. Crew members told about issue not fixed on time hence 16+ hours was tough to spend. 3. Food in domestic Air India flight was better but in international flight it’s not good.

The flight was fine. The cancellation of my flight and the proceeding service was ABSOLLUTELY AWFUL! When my connecting flight was cancelled, there was nobody there to help reschedule a flight, get a refund, find our luggage and above everything else, they kicked us out of the airport since we didnt have a valid ticket (since it was cancelled). here i am 8,000 miles from home, after being on a flight for 15 hours and face 6 hours of delays then finally cancelled and kicked out of the airport with noway to get a refund, find my luggage, get a new flight (except just by a new ticket). And oh, this is at midnight local time. AWFUL.
