Tips for multi-destination flights

This is Baguio’s airport. It’s been open to commercial flights since November 2022 (previously only private and military flights). It was "officially inaugurated" in December of the same year with a regular P.A.L. Cebu-Baguio round-trip flight, which was discontinued in July 2024 due to low demand.
Nothing since then, and no info about future flights.

What you need isn’t a multi-destination flight, but a Paris-Manila round-trip on Vietnam Airlines with a long layover in Vietnam. That’s the simplest option and probably the cheapest too, since stopover fees in the airline’s hub city are usually low—sometimes even free.
