Freshfields Bruckhaus Deringer has taken a role alongside a trio of US firms on the $3bn (£2bn) tie-up of United Airlines and Continental Airlines, reports The Am Law Daily.

The deal, which creates the world’s largest carrier by passenger traffic, will see the merged company retain the name United. Both carriers had previously considered a merger two years ago, but that deal collapsed over concerns about oil prices and $537m (£353m) in first-quarter losses by United that year.
