Very simple review... just don't use them unless you want to be ripped off, delayed, cancelled or you love to play silly kids games on board (whenever you actually do get on board!). And don't ever try to cancel and get a refund as you're money is long gone. Use PAL.
When the airline competition in the Philippines stopped making certain trips Cebu Pacific raised their rates for those particular trips. One day Cebu Pacific could make a profit charging a fair price. The next day they were the only airline available so they increased their price 4 times more expensive. For the route I travel regularly when the competition returns I will fly Air Asia or PAL. Until then I will take a boat. Also should be mentioned if you have a problem with Cebu Pacific you will not get to talk to a live person. No phone number you can call, no email you can write, all you can do is use their robot chat which will never put you in touch with a human. Their web pages is often glitchy and their app seldom works. You should avoid this company.
