Too many carryon bags with size of checking bags. Because of that space was not there to put carry on backpacks.

Nice crew.flight delay fromBKK for some ground prep issue I guess, crew serve well to guest, and respect to guest as well. As usual AC is old,and nt much comert in compare to other rehional airliners.other than that.all good

Flight was on time.food is as usual good.Aircraft is old.old A320, seats aithout any display.crew serve well

When flying from Indian Sector, should be more prepared with Indian food

KAYAK Real time status update is not accurate.the flight inbound rejected and go around.and came back and land. Delay abt 30 min.still shows ontime.track ur self if u wana real time.and cabin crew s are nicer. Aircraft is jst ok.old airplane.and in midflight ,seems have some compressor issue.airconditioning was nt work properly either.I could litarary see guests were cheking if AC is working.bt on landing it start to gv cool.which probably some one intentionaly kept .which was so bad.even breathing was bit difficult.otjer than that.for me all ok.

This leg of the trip was smoother than compared to the initial trip. Sri Lankan Airlines still have much work to do to improve the overall travel experience.

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

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

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

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%
