Honestly guys, I speak the truth, none of the low cost airlines in the Philippines are better then any other. Zest Air vs Cebu Pacific Air vs AirPhilExpress vs SEAir = expect the same service. Realistically they will all leave you high and dry, change schedules, have delays and fail to inform you about whats going on. Sometimes your lucky and get a hotel or a jollibee burger, or they leave on time and it all goes without hassle. If you look for reviews of all these airlines you see the same story and pattern with all of them.
Unless you want to pay PAL prices, then choose the cheapest flight on the most suitable schedule.
Consider the low cost option like a bus service, except with beautiful girls instead of a grumpy bus conductor.
