My wife once had an argument with check-in staff who wanted to charge her for having excess baggage, as I gather she successfully argued that as she weighed just 53kg the extra baggage was less than the difference between her and some other passengers. The nice thing about this method is that business travellers could get lower pricing because they generally travel without much luggage. Plus my wife and I are generally 10kg under the allowance when we travel, so it could work out economical for me if bought to Europe.
