Do you know the maximum baggage weight for an international flight of Qatar Airways and Aviance Airways?

You could send me a link to the site. I just need to know cause baggage weight is not written in my tickets. I have Qatar Airway ticket from Manila-Doha-Madrid and Avianca ticket from Madrid-Medellin. I am starting to pack for my trip this weekend. I'll be In colombia for 6 months. :-|
