Thank you all for your help! It is very much appreciated!

If it is no trouble I have a few other questions to ask:

1. Flying internationally from Canada on KLM, I am aware I am allowed two pieces of checked luggage, how much can each suitcase weigh?

2. Is it okay to lock my suitcases? (Note: I will not be entering the US)

3. Is it acceptable to take pictures inside of the airport and of airplanes from inside the window (I know it may seem like a foolish question but I just want to make sure, I love photography (Note: these will not be US airports)

Thank you in advance, as you can probably tell I am not an avid flyer - the last time I was on an airplane was 5 years ago so please excuse the 'amateur' questions.
