He would be cruising at between his normal operating mach number and MMo but he would have been travelling the bulk of the way down a huge jetstream to set these kinds of speeds.

Why can't they go fast when I'm on that flight! I've been on UA816 from SYD to LAX at least a half dozen times. It typically lasts around 13 hours, I'd like to see how long this one took.
