The problem the ambulance chaser will have (not including not being able to chase jumbos) is that setting a fuel surcharge in itself is not illegal.
The reason for the ridiculous fines is the manner in which Virgin and BA and KAL went about the surcharge rises. Collusion before the event is illegal and leads to the 'price fixing' problems. Raising the price of the surcharge is not. Just badly done.
BA, bless 'em, have screwed up again and got their fingers burnt. They've paid a hefty price for it. Lets hope that stupid american lawyers don't see this as a money generating bandwagon to jump on. Let them concentrate on the appalling state of their own aviation industry and represent the thousands of workers who have had their pay and pensions trashed by chapter 11.
