I tried looking at the site, but didn't find the answer. I'm moving, so I'm checking in quite a few bags. Called MPO, they don't have a clue. Kept just repeating off the website. I rarely check more than one bag and it's almost never over 23 kg, however:

1) Is the weight limit of each additional bag (over my allowance), the same of the limit for my ticketing class? (Since I'm flying in J, my each additional piece can be 32 kg?)
2) What's the maximum number of bags I can check? Right now I'm looking at five checked baggage, but it may grow to six or seven…
