At FL450 our indicated speed is only about 270kts but our TAS is about 510. We also use a great circle route when going far as it reduces the distance travelled by using the earth’s curvature to our advantage.

My only comment on your daughter's flight, is that she actually is travelling further than the ground distance, because the jet is describing an arc above the earth. She's probably 5 miles up, and going around a circle (earth). Considering the diameter of the earth, I'm guessing that someone else can justify that the groundspeed is only infinitesimally decreased. The dAlt , does have something to do with Mach #, but maybe not enough to make the flight early. You would think that a 150 mph tailwind would though. Remember seeing those Flight Arrivals boards update? That's the sound of the result of the navigator's recalc of arrival time (probably just some Garmin device, though).

While spending 6 hours monitoring my daughters flight from Los Angles to New York, non stop, on ADS-B exchange.com and Flight aware, I'm wondering what the odds are that she flew within one mile of directly overhead of her only sibling (sister) house at the halfway point. I alerted my second daughter and she went outside and heard her sister pass overhead above the solid cloud deck. Second, while watching the flight experiencing a 150 mph tailwind over the Midwest I'm wondering, does an airplane benefit 100 % of the tailwind as increased ground speed or is there some percentage of loss due to the thinner density of the air as compared to a boat floating downstream in a river? See what happens when you have too much recliner time. 😕 And to Luis, you aren't going to let that tailwheel win, are you?
