How far will I travel? A prize for the correct answer

I leave Spokane on June 8th for San Francisco. The next day I leave from San Francisco to Tokyo. Approximately how many miles will I fly one way, from Spokane to Tokyo? The first student to post an answer within 100 miles wins a prize! I suggest you use the internet to calculate mileage. There are a number of places to try including http://www.airtimetable.com/Air_mile_calculator.htm or

Also, you might need to know the airport codes. Here they are: Spokane (GEG)
Tokyo/Narita--(NRT); San Francisco: (SFO) Note: are airport codes.

I'll need to receive the correct answer by Tuesday, June 3rd. There's a candy bar waiting for the winner. Please post your answers here and be sure to include your first name or initials. Miles, please!
