Well, this airport is one of the oldest airports in the country and also the third international airport in the country. There are two terminals but both are not connected to each other and are on opposite ends. T1 is relatively old and it's high time for a renovation. T2 is pretty good and caters to selected domestic and complete international traffic.
Very high passenger convenience fee for passengers travelling out of this airport, it is nearly 597(domestic) and standards are no where near DEL, BOM or BLR whose convenience fee is less than 1/4th of this.

This airport mostly handles narrow body aircraft. Wide body movement is really less, occasionally just a SriLankan a333 and a daily Emirates 77W are visitors. Other carriers seldom operate wide body aircrafts to this airport. Again, this airports international destinations are mostly to the Middle East. As of now, no scope of European Expansion (for non stop flights). There are 3 other flights to South East Asia tho (Sri Lanka, Malaysia and Singapore).

Hope this airport gets privatised soon, then only it will develop and become a better hub like BLR or atleast like MAA or CCU.
