The other problem with CP is baggage restrictions
[QUOTE=Idler31;1203156]The only question I have is: do Cebu Pacific have any unreasonable requirements concerning (for example) seeing the booker's credit card at check-in time? Or any other quirks and niggles that might interfere with plans?[/QUOTE]About six months ago I bought a ticket online with CP for my squeeze to travel Tacloban to Manila. No requirement to show a credit card, but she got a big surprise on luggage. For many of their cheaper tickets CP permits only one small carry-on and no checked baggage. Squeeze had to pay some exorbitant amount for one extra small piece. Fortunately she had some cash with her.
Make sure you check the baggage restrictions for the ticket class you purchased and communicate this clearly to the girl. If they're not frequent fliers they're unlikely to know this stuff.
