Very poor. The flight was delayed for over an hour. Also, our baggage, including that of many passengers, approimately 180 bags did not arrive, and we are yet to receive it.

Poor, They have damaged my luggage and I have filed a claim at Colombo airport. They promised I will be in touch by the team within next 2 days but there is no One contacted me at all after 1 week. I then follow up again and received an email acknowledging my claim and claimed that they will reply in 12 days on investigation. Again, no response at all after that… Very disappointing…

All good, on time, depart.only bad side was, airxraft is too old to be in business.hope ailine will manage somethinv somewhat.all good

Was good, comparatively. A330, with good crew set.on time depature. And crew try there best, to make thing efficient.

Spesific ,Crew and cabin manager, look after all pax on board despite being in a old A320 equipment.Got free seat upgrade as well,but old style seats, no much comfert on it.But food and the spesific crew, was amazing.maintain airlanka standerd.the cabin manager, who was so much keen,keen operate as per SOP.

The staff was absolutely phenomenal but the other elements of Sri Lankan Airlines need some serious adjustments. The day started off with terrible news that the flight was cancelled from Male and that the plane went to Malta. As an American, when such delays occur, the airlines find suitable ways to accommodate their customers such as putting them in an Airport hotel or lounge while waiting for the next flight. A 1.5 hour trip turned into 12 hours with no accommodations from the Airlines except a ticket to eat breakfast. For such a Billion dollar industry, a cheap breakfast is an insult toward the customer and something greater should have been done.

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.

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.

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

Crew was polite. Ground crew was prompt in informing about the flight delay. Boarding process was ok. There was no entertainment on the flight. Blankets were not available for an overnight flight. It was very cold & blanket was given upon request. Food was average. It would have been better to serve breakfast instead of a late night dinner as people like to sleep & serving breakfast before disembarking in the morning at Singapore would have been much appreciated. Seats were ok. Plane was old.

Non reclining seats on a 14 hour flight. Crew skipped drinks for my row at least twice.

Information about when boarding would start was missing. Ground staff wasn't ready to provide any information with the answer being in the next 15 minutes any time we asked. (Took 2 hours)

I don’t like air India seats are too small and staff are not that nice

On time boarding, proper information, friendly and cordial approach of staff, particularly crew members and the most important timely available of checked in baggage after arrival.

Flight got delayed by 3 hours but no compensation or anything

Booked thru Kayak -> Indian Eagle. One leg of flight was cancelled after check-in (CCU to Del). Rebooked thru Indian Eagle cancelled again and rebooked. Cancelled once more now scheduled for CCU-BOM-JFK on Jan 18th. Let's see if this gets cancelled again. Would not book any tickets thru India Eagle - they are just a ticketing intermediate and for questions they ask you to call Air India. They "request" booking but apparently I got bumped after ticket was confirmed. Much better to book directly with Air India - avoid Kayak and Indian Eagle. I paid for Travel insurance can't see it any more on Indian Eagle site to contact.

One of worst flight. No Videos/Movies. The Seats are not good.

Chaotic/Crowded check in. Delayed departure from LHR, resulting in a very delayed Dinner service. Since takeover by the TATAs, Air-India has become Uber commercial and not in a good way, but more like Ryanair. Most seats are now sold and at too high prices (£24 add on for a single windows seat). The promised transformation into a better (clean), efficient and professional airline is nowhere in sight ☹️ Thanks

Food is okay, could be better - Economy and Premium economy. Great service , good crew. Overall great improvements so far and , lot of potential to be on par with other top notch airlines
