Thiruvananthapuram, June 29 : Thiruvananthapuram: Kerala boasts of being the only state in the country with four international airports, while a fifth one at Sabarimala is on the anvil, but the sad fact is the fourth international airport at Kannur is presently having a hand to mouth existence.

The Kannur airport revenues hit rock bottom with just two airlines - Air India Express and Indigo - operating a handful of flights.
