This has to b worst airport xperience for me. Poor signage and lack of system cause so much confusion and congestion at every point from luggage check-in, custom to boarding. Poor customer service too
Worst airport where you will try and get charged for using the toilets, men outside trying to charge you for outing your bags in a car, not a lot to do
The cheapest and the most convenient way to get from airport to Colombo and back is UBER. Avoid street agencies providing transfer services. they want double price
