Yeah... at 11 miles, it was longer than BFI-SEA or the shortest scheduled commercial flight (Westray-Papa Westray in the Orknies, ~2mi), but pretty impressive for a 747. Especially when many carriers fly 757s from the east coast to Europe.
For the next few hours, there's a little route map available on flightaware.
