I happened to travel to dubai before one year and cochin international airport was the departure and arriving port.the airport location is bad, it is too far from the city and I get major traffic in the way.the staffs at the airport both domestic and international are extremely rude.only certain sections of the airport are clean.domestic departure is extremely filthy.also the toilets are in really bad condition.even the hand wash area seems to be very unclean.there is no fan provided at the receiving hall and visitors lounge.lack of good restaurants, poor wifi connectivity and poor taxi facility is another main disadvantage of this airport.the immigration procedures are extremely bureaucratic.i would not recommended this airport to anyone
