American Airlines does still offer 'proper' First Class across the Atlantic.
On many of its B777 flights you can enjoy Flagship Suite - a pod-like seat that converts into a fully flat bed or and office (the seat swivels round to a desk complete with power socket for lap top.

From early next year American will switch to a two-class config (Business Class and Economy) on its 767s but the 777s will continue to offer First Class.
