As for your itinerary, are you sure you don't want to go to Boracay? I wouldn't miss it if I were you. Sagada is way too far. Will take you about 7 hours or more. I don't think there's an airline that goes to that area.

You can probably do 3 days in Palawan, 2 days in Bohol, 2 days in Boracay and 2 days in Manila.

You can check the ff airlines:
