SunSea etc.
I'm aware of that. There's also a few A320's operating under ETOPS. However, my point was that the 737 doesn't operate very often under ETOPS, whereas the 767 (or A330 for that matter) does so far more regularly. And I chose the 767 simply because it's by far the most widely used a/c type fra transatlantic flights. Indeed, the 747 is seeing decreasing usage over the atlantic, in favour of more direct point'to'point routes flown by smaller twins such as the 767, 777 and 330. To my knowledge only a few airlines operate the 747 from Europe to the US east coast, AF and BA being some of them. But they are serving huge hubs FROM huge hubs, and are heavily dependent on lower deck freight to make the crossings profitable (or so I've been told anyway)
