Bandaranaike International Airport (BIA) situated 34km North of Colombo (capital) is the country’s main international airport. Mattala Rajapaksa International Airport (MRIA) is a recent addition (2013). Sri Lankan Airlines (Flight Code UL) is the National Carrier.
There are many Taxi Services offering transfers to and from the airport. Wherever possible, requesting the driver to use the expressways is a good option to avoid the gridlock of suburban traffic. You will need to pay the road tolls, which are modest sums and well worth the time saved during the commute.
