I am planning to enter Philippines on Balikbayan 1 year stamp. Do London/Manila airport ask for return flight ticket from Manila to UK? My return journey will be after 1 year, so I can't book return ticket. Is there any flight service from Manila to UK, which can be cancelled and fully refunded?
The first question yes they ask for a return ticket...... Buy a cheap return ticket to nearby countries, we call it a throw-away ticket. Expedia may fully refund a ticket, but better check with them. I came here with a return ticket, cheaper than a single. Just bin the return part once safely thru passport control or keep it in case you change your mind.
As British nationals don't need visa for 30 day stay in Philippines, shall I book return ticket within 30 days, even though I am requesting Balikbayan stamp at Manila airport?
The return date can be after 30 days... no problem. (I take it you already realise that your Filipino partner must enter the Phils on the same flight as yourself, in order for you to be able to ask for Balikbayan stamp ? I would also recommend you take a copy of your marriage certificate to show to immigration ).
