I am aware that there are baggage rules. But I am all confused with this "Checked" and "Carry" rules. I want to bring a lot personal things like soap, shampoo, lotions etc. (Something that will allow me to live normally for a week, it will be my first time in Makati, and more so, my first time boarding a plane) but after reading guidelines all over the internet, all the rules got me confused.
Checked baggage means those bags that I won't be able to access during the whole flight, right? While the Carry baggage are those things that I can bring and hold inside the plane...? Did I understand those correctly?
Any bad experiences while boarding in a plane? Any tips you could give me? I don't want to look so ignorant there.

Any tips would be appreciated.
