me too.
Most airlines kept cancelled the flight to Manila.
First, I booked Cebu and the flight should be on June 1st, but, cancelled and
no flight schedule up till now.
So, I changed to HK Airlines, but, still cancelled the flight 2 times and now waiting for the flight on July 24.
After checking Skyscanner, the flight from August 1st seems more stable and more airlines provide the tickets.
So, if you can wait, you can book the flight which departs in August.
