I received an email yesterday from somebody at a hotmail address mentioning ScotJet. ScotJet plan (apparently) to run A330s to NYC and YYZ with fares starting at £89 each way. The plan has been described by others as "embryonic". Without prejudice or comment, I invite you to draw your own conclusions. My colleague made a passing reference to it in some (but not all) editions
this morning.
Hope this helps.
