[Captain Aslam]

I am a seasoned traveller & an old ALTP/FAA- ATP license holder.
I was travelling through a small Airport and after cheking-in,entered the Departure Lounge with more than an hour to go for the scheduled departure.The Gate was not mentioned on the Boarding Pass. I checked the 4 Gates at the Airport and none of them showed my Airline name.
I positioned myself in front of Flights Information Display Board which showed against my Airline the Flight No,Destination, Scheduled Departure Time but no Gate No or status.
I heard an annoucement for departure of a flight to destination same as mine & saw passengers lining up at a gate in front of me. I went also but found that it was a different Airline Flight. The Display board showed no change with respect to my flight.
About 17 mins before the scheduled departure I saw the Display board change from local language to English showing "Last Call". I spotted an aircraft parked at a gate behind me and rushed through it to the Tarmac in a minute or two to see the Door of Aircraft about to be closed. But a guard did not allow me to go to the ladder.
I showed my Boarding Pass & said that my luggage is on board. He said it was already off loaded & pointed to it on the tarmac.

The Airline staff blamed me for "missing" the flight & offered no help

As a result my stay perforce was extended & I incurred considerable expenditure on transportation,hotel, food & a new ticket.

I susequently lodged complaint which was also directed to the CEO of the Airlines. Response was received after more than 70 days regretting the incident but offering no compensation.So I have sought Legal recourse..

I shall be grateful to know the following:

1.IATA/ICAO defination of departure time
2.If a passenger is missing / fails to report at the Gate what action is mandated by IATA/ICAO
3.Regulation under which, a passenger if missing, all luggage must be unloaded and each passenger must identify his/her luggage.
4.Rule on time frame by which Airlines must respond to a complaint.
5.How to obtain the actual Official Time of Departure of a flight from an Airport
6.The Airline maintains that "Departure Boards and other airport facilities provided at an airport are the responsibilty of that county's local aviation authority and not that of the airline".Pl confirm that the ultimate responsibilty rest with the airline and quote any ruling on this.

Would appreciate an early response.
