if fr can operate the route, using whatever a/c they can and make money, then good luck - but the pitfalls will be HUGE, and there will be many, many, many of them. i still reckon that even with a 757 with 2+hrs etops clearance (61/2 flt) and a full 235 pax, you will be pushing the limit on the a/c range. and thats assuming that they will get etops certification for there a/c, crew, and mainanence - all of which takes a long time to obtain - and a hell of a lot of effort to retain. if an experienced etops operator like one of the big uk charter operators last year can have there etops cert, suspended - then fr dont stand a big chance on there lack of engineerig experience alone.
