Commercial flights bound for Europe have been taking off late from the States but arriving on time or early, thanks to a more powerful jet stream, strengthened by the arctic air mass that settled along the East Coast last week.
A Virgin Atlantic flight that left from JFK International Airport this week an hour and 13 minutes after its scheduled take-off time nevertheless arrived at London’s Heathrow Airport right when it was supposed to land, reports the Washington Post.
The planes didn’t break the sound barrier because it was the air moving them so quickly, not their engines. The report compared it to someone walking on a moving walkway at an airport – the person is moving faster because of the walkway, not because they’re walking faster.
Each winter, the jet stream intensifies. It also grows in strength at night, when the lower atmosphere starts to cool, which happens to be when many flights from the East Coast take off for overnight trips to Europe.

I did a little search and found a discussion of the comparison:
Interesting conversation.
