Thanks for all good info.

I should point out I am not concerned about paying for the extra pieces mainly due to the fact it will cost me way more to replace all the things I would need to toss than pay the $150 required. I have packed five bags all to the gills are almost 32 kg a piece. These five are not possible as carry ons being they're all too large for the cabin. I know some airlines do limit the number of checked baggage hence my concern.

I am looking at a sixth piece right now, I may be able to fit the rest of my stuff into that and it could be carryon. Also cleared an upgrade to F, so perhaps they'll be more generous.
