Because return flights are a lot cheaper than two directs - and because I want to go to a few countries in Asia - I'm planning to book a return flight from London to Manila, to stay in Philippines for 20 days (on a free 30 day visa) - but then I'm planning to fly to some other countries and come back to Manila to get my flight home.
Do you know how long I would need to be out of the Philippines to be eligible for a second visa in order to fly back?
