Booked flight tickets

Wow, this is the first time I bought anything over the Internet using a credit card. Well, it is for a good cause: Am going to KL for CK's wedding, so using Air Asia to go there. Flight tickets are WAY cheaper than MAS, so hopefully can have more $$$ for shopping. I think I only have to pay RM269.?? versus RM600+ from MAS. Well, have to sacrifice a bit of comfort for money. What to do... Flying there on Friday the 13th! Hopefully there's no one named Jason in the welcoming committee.
