Twelve sectors a day!
Really? Who does that?
Low cost UK/Europe - EZY and RYR utilise aircraft from 0500 to 0200. Average use is 10-12 sectors a day. They don't make money on the ground. Turn times are 0:25-0:30 mins.
Of more concern is the implications for ETOPS for the 787. Are the ETOPS authorisations unique to to type or type+type of engine? It would seem pretty harsh to pull 787 ETOPS based on say a number of GE shutdowns if your fleet was fitted with Trents. Anyone know?
