My friend works for a large international company which (albeit begrudgingly) puts it's employees travelling on company business, up the front for fear of claims against the company in the case of DVT.
He does lots of business travel, and says the only reason he's still travelling up the front in these harder economic times, is the fear his company has over any future DVT case against them!
Maybe a cunning ploy BA etc can take advantage of to keep them all up the front in the posh seats!!??
My thoughts go out to the people who died because of this, all just coming home from holiday. Hopefully research and awareness etc will prevent further cases.
