São Miguel is accessible by airplane, only. The international airport on this island is located in the capital Ponta Delgada, code PDL. A flight from Lisbon or Porto will take 2.5 h, from Toronto 5.5 h, and from Boston, Brussels or London 4.5 h. There are not many airlines offering international direct flights to PDL, so it is possible that you have to stopover in Lisbon or Porto. There are several daily flights between São Miguel and the Portuguese mainland, which means that you are not dependent on a particular day of the week for that part of the journey.
