the airport tax is 750 pesos...i found out it is advisable for quick passge through the Uk immigration and Helth control area(required for all who will be staying for more than two years in the UK, such as a spouse) to have an x-ray examination done before leaving the Philippines...then show it to the health officer at the helth control so she/he won't have to be x-rayed...my Terry waited longer for me outside heathrow airport..cause i had to wait..and be x-rayed
