Middle Eastern airline, Etihad of Abu Dhabi in the United Arab Emirates, cancelled orders for four Boeing 787 Dreamliners in February. The carrier still has 31 Dreamliners on order.

With the problems Boeing has had with this program, I'm surprised more orders haven't been canceled. But now with the fuel prices going up like they are, a more fuel efficient airplane is just what everyone needs. The 787 and 350 cannot come fast enough.
