AD PLACEMENT — CONTEXTUAL
Most connecting passengers stay within Terminal 1, walking between gates after a security re-screening point near the transit desk. Terminal 2, opened to relieve congestion, is a separate building reached by a shuttle bus or a longer outdoor walk, and passengers connecting between the two terminals should allow extra time as it is not directly linked airside.

Is CMB easy to connect through?

Colombo's Bandaranaike International is a modest single-hub airport built around SriLankan Airlines' overnight bank of departures, so most connections are straightforward within one compact terminal complex. The main challenge is the airport's notorious pre-dawn congestion, when security and immigration queues can back up significantly due to the concentration of flights between midnight and 4am. Most connecting passengers stay within Terminal 1, walking between gates after a security re-screening point near the transit desk. Terminal 2, opened to relieve congestion, is a separate building reached by a shuttle bus or a longer outdoor walk, and passengers connecting between the two terminals should allow extra time as it is not directly linked airside.
