I recently spent 21 nights in the Philippines

i used Cathay Pacific London Hong Kong Manila going Clark Hong Kong London coming back

Even though Dragon airways is part of Cathay Pacific they still made a big deal about it when i checked in at London Heathrow

how long you going for?
do you have a visa?

When i informed them that i had a confirmed departure dated ticket with Dragon Airways for my return they then backed off a bit
They should have known that already !

I can recomend Clark airport to everyone who wants to avoid the hassle of using NAIA Manila
