Lots of A330s and A340s fly the Atlantic daily. US Airways flys the A330, for example.
Airbus ownership, IIRC, is 20% BAE and 80% EADS. EDS ownership is Daimler-chrysler (30%), Aerospatiale Marta (30%)(French govt & Lagardere) and CASA (5.5%)(Spain), and the rest is for investors according to initial plans.
