Yikes, that's insane!
Is $4400 the round-trip or one way? Because I only think I'm going to have overweight baggage on the way there, not on the way home.
For all of the other regions they have a set price for an extra bag between $100-200. Do you think that for an extra bag between Asia-Europe it will be $1320? (I'm calculating an extra bag as an additional 20kg) I don't understand why they don't list it in their table.
