Lufthansa & Swiss are great IMO, they have also very good policy for upgrades: If the economy class is overbooked then the frequent fliers would be upgraded to business class in no charge.
Their computer rates the frequent fliers and the top ones would be 1st for this automatic upgrade.
I normally get this upgrade 1 out of 4 legs. 25% of time. If you book business and it is overbooked you are upgraded to first, happen to me several times.
