@debradownsouth what i have seen and checked again now is that this is the price for cargo hold. Isn't is the luggage area and not special Cargo?
Anyway, i will give them a call, but at least from what i understand 200$ is for hold cargo, which, again, as i understood, is where the Baggages are.
So it may be with luggage, but pressurized and climate control. It did worry me that it could drop ti 41C, but that's rare.
EDIT: " Passengers flying on our Boeing 787 aircraft, please note: The temperature in the cargo hold can drop to 5 degrees Centigrade. "
I meant 41 F, which is 5C. But I didn't fly on 787 so moot point anyway.
