After reaching SFO and checking -in, I found that United States don't have immigration inspection for passengers leaving United States. But, before baggage inspection, I had my passport checked.

I headed for a lobby to board Korean Air flight for Incheon. Then, Korean attendant checked passengers' boarding passes. Chinese elderly couples were also asked to show their boarding passes and passports. But, they didn't know the word 'passport' in English. With the help of other passengers, thay understood what 'passport' means.
I boarded the airplane.
Though I could see daylight outside the airplane, September 3rd came when the plane passed over International Date Line.
