Silverjet has 180 minutes ETOPS
Thanks. Well that solves our fuel issue. Regardless of what the comparison was between Y7 and MY, MY clearly spent significantly more on fuel due to not being certified for ETOPS. It's unlikely they would have been certified anytime soon either given the massive number of mechanicals, diversions, and tech issues. The white ghost seemed to be grounded more than it was in the air, plus the announced idea of using one of the 762's as a "spare" is clearly not a financially responsible use of assets.
Even given all this, I still think it's possible that Y7 is only trailing MY in time. Time will tell.
