I'm looking at an itinerary currently as follows:
Philippine Airlines: Tagbilaran -> Manila (T2), landing at 1815hrs
Singapore Airlines: Manila (T1) -> Singapore, departing at 1850hrs

Two questions:
* Would Philippine Airlines allow baggage to be checked in to the SQ flight?
* Assuming the above works, would there be sufficient time with a taxi to transfer to the SQ flight or do I plan to spend a night in Manila (1850 is the last SQ flight out)?

Thoughts appreciated; thanks.
