Hi I need a cheap throwaway air ticket so I can get back in, the best the agent can do is P2,300
Cebu Pacific used to have tickets to somewhere in Malaysia for 1500 pesos. Maybe you could check for ferry tickets from Julo or Zambo to Malaysia as well. They might look at you like you're an idiot for going to Julo but it meets the requirements.
To get back into Philippines you just need an onward ticket and not necessarily a ticket back to Hong Kong. You can buy a ticket to Kota Kinabalu with Airasia for PHP 1400 with departure around 21 days from today.
Air Asia - Clark (Luzon) - Kota Kinabalu - online around 999 PHP, (ex wednesday march 6-2013)
no hidden cost like tiger or Shabu Pathetic
The cool thing I had with Tiger was that my throw away flight was canceled and they automatically credited it back to my debit card. So....I met the outbound ticket requirement and it didn't cost me anything!
