There is a minimum allowance specified within the fare rules: (

Two free pieces of 23 kilos each shall be permitted. Additional allowances may apply. Refer to individual

Extra baggage allowance
As an Emerald frequent flyer you can check in one additional bag for free in addition to your ticketed baggage allowance when you fly on oneworld airlines. If your ticket mentions a weight allowance, you can check in an extra 20kgs (44lbs). (This benefit is not available on British Airways 'Hand Baggage Only' fares on select short-haul routes.)
So, through the entire journey you should be entitled to at least 3 x 23kg and likely more.
