Thanks but do you mind telling me where you've made changes?

And erm, it only allows buying one ticket. After that, they keep asking if I want another ticket. But they never ask for the personal details anymore.

Just a question Zenghoong.

Why a 3D array for the seats?

The first is for the flight, second for row, third for column

do u have any diff utility like vimdiff or beyond compare or emacs : diff please use it man u will able to understand where i made changes u want me to tell u everything please learn these tools also compare tools

Thats fine but one more problem. it only allows buying one ticket. After that, they keep asking if I want another ticket. But they never ask for the personal details anymore.

check the logic dude i haven't gone though the logic of the code. I just make ur code in a position where it can build successfully

do you mind going to my other thread. Need help with that question.
