If we went straight out over the Atlantic is that not an ETOP'S issue?
Yes it is ETOPS, so is the A330 and so are the crew. The routeing will be cost determined on the day depending on prevailing winds etc. On the day the operations department will file the best route in the prevailing circumstances. However if you want me to guess the route now, it is : Irish sea, Ireland, Atlantic Ocean (lots of it.)
