Most of my trans-Atlantic trips have been on the 767. While it's a little smaller than other wide bodies, this is probably the most under-appreciated airplane Boeing has ever built. Aside from tiny overhead compartments, this is one airplane where Boeing got it right. Before the 767, trans-Atlantic flights were operated with three or four engine airplanes. The 767 proved ETOPS (extended twin engine operations) to be safe and successful.

Your over water time on most crossings is actually fairly short. The time spent on the North Atlantic tracks is only about 3.5 hours. Often trans Atlantic flights spend more time over Canada then they do over the ocean. ETOPS flights are designed so they stay a certain distance from diversion airports at all times. For example, most 767 flights are 180 minute ETOPS meaning they have to be no more than three hours from a diversion airport. You've got plenty of divert points along the Atlantic including a return to Ireland, Iceland, Greenland, and Canada. Maintenace checks are required on the engines prior to each crossing.

As far as the comfort of the 767, many prefer the 2-3-2 in economy. Premium cabins are a little tighter than the bigger 777 but not uncomfortable. Some of the airplanes are a little worn, but not un-safe. Delta did a major renovation on the 767 interiors where it looks like a brand new airplane. Many of the newer 767s have the 777 interior.

Most 767 pilots love the airplane. Many comment that it flies like a Cadillac. It has the largest cockpit of anything built by Boeing or Airbus. One thing to remember, no professional pilot will take an airplane if he or she feels it's un-safe or not fit for the flight. The 767 is still the most popular plane crossing the Atlantic.
