lesson one in other people buying your plane tickets: never assume you will get the same luggage allowance as when you came. Because that'd just be logical.
i.e. I brought 40kg of stuff. I have a bit less to take back. but they went and bought me tickets with 20kg.
so I am gonna have to pay for that. :| grumpy grump grump.
if it were the other way around, or even just 20 for both, that'd be fine. I'd have planned for that. but letting me bring a shit ton of stuff and then basically saying I can't take it back home...
