I noticed that many transpacific flights bound for JFK today, are making their initial crossing into the USA over Northern California. This is pretty rare, most times the crossing would occur over YVR, or ANC. I assume this is based on a different wind pattern today, etc.

Quoting Flyguy1 (Thread starter):

When the seasonal jetstream winds are especially strong they tend to be further south. As such, the westbound crossings go *very* north, often close to the North Pole. The eastbound crossings go very south, often splitting the difference between Alaska and Hawaii and making landfall somewhere between SFO and SEA. Since the winds can go in excess of 100 kts, most airlines dispatch use the huge push and send the aircraft on Mid-Pacific routings.

So, despite being a longer distance to cross the mid-Pacific as opposed to great circle, the push from the jetstream still cuts the flight time significantly.

The jetstream was fantastic for trans-pac flights this week. I believe it was Sat. when United and other carriers had their Asia birds arriving in SFO 60-80 min ahead of schedule. And the westbound planes were easily able to fly north of the jetstream all arriving on-time or early as well. Was the perfect situation.
