alas legislation encourages people to sue if you look at my earlier post, legislation says the airline is responsible regardless for approx £103,000 of proven loss, therefore every lawyer in the country would give it a go to prove their client had a loss of at least thing amount as it is easy pickings.
plus of course the most important bit, they will all be on conditional fee agreements (no win no fee, invented in the US but in the EU largely only existing in the UK and Eire) whereby the solicitor will get a nice cut (between 20 and 100%) on top of whatever the passenger gets.
