Flying between Manila and Hong Kong : Cathay Pacific, Philippine Airlines or Cebu Pacific

I consider myself a commuter of the Hong Kong-Manila-Hong Kong route. I fly it at least once a month, up to weekly in some months. Flying these flights gave me a chance to compare the airlines flying those routes. Comparing these options solely on the service is unfair, as Cathay Pacific is a 5-star airline, while both Philippine Airlines and Cebu Pacific are 3-star airlines. But don’t worry; this comparison will dig deeper than that. Keep in mind though that this review is focused on their Hong Kong-Manila and Manila-Hong Kong flights.
