I took four flights: Clark to Coron and Coron to El Nido (and return flights) - each flight was an hour or more delay. one flight return to Clark due to Weather (not your fault). Service from staff is horrible as they provide no answers. Their App is also horrible and less than helpful if you have any true needs. Basically, you have no customer service. Buy a ticket and good luck and have patience. I think you have customers because we have no choice.
Recommendation: Book flighst with plenty of time for surprises
