Take a flight to Manila. You may have to spend a night in Manila on your outward journey because onward flights to Boracay are limited.
Fly Philippine Airlines from Manila (Domestic Airport) to Kalibo Airport. (The flight takes 30 minutes and costs about 3,000 Philippine peso return).
From Kalibo Airport takes the air-conditioned bus to Caticlan and the boat from Caticlan harbor to Boracay (the bus trip takes 90 minutes and the boat 30 minutes; combined ticket Pp140).
Various charter companies fly direct from Manila to Caticlan Airport (Pp4, 000 return; 60-90 minutes).
As there is no jetty on Boracay, you have to wade ashore from the boat, so wear something suitable!
