Air India Express from Cochin to Dubai on 25/11/05. Aircraft quite new and thanks to being seated in one of two emergency exit rows lots of leg room. Despite travelling on a low cost airline you nevertheless are served a snack consisting of sandwich cake fruit juice water coffee or tea. On the downside the passenger next to me was allowed boarding in a clearly less than sober state and the crew continued to serve him hard liquor throughout the flight (alcoholic beverages available on a for sale basis). He even managed to complete the entire flight without ever having availed of the seat belt. Also despite being a non-smoking flight crew were quite relaxed at seeing the lavatories being used continuously as smoking rooms - with the obvious and objectionable result of extremely bad air quality in the cabin throughout the flight.
