Domestic flight Colombo to Jaffna vs the A9 bus — when is the ticket price worth the hours saved?

If your Jaffna days are few, flying often wins because the A9 eats a large daylight chunk even when traffic cooperates. Buses remain the budget default and are straightforward when you can spare the travel day each way. Factor airport process and city transfers against bus-station timing — door-to-door matters more than airborne minutes. Check current domestic schedules the week you travel; they shift. I will not quote ticket prices here because they move. For three solid days on the ground, many visitors fly at least one leg.
