Travel plan for debconf5 (planning schedule)

Air ticket to Finnland is expensive...

• Cheapest one is using Malaysia air, but it losts too many time.
• Finnair won't fit in schedule from/to Narita airport.
• Air France is suitable and cheaper one, but it spends time. And I couldn't get milage from this line.
• LFH or SAS are appropriable for me, they're star-alliance members. Little expensive.

Hmm, I'll use LFH or SAS. NRT-(CPH, FRA or MUC)-HEL. The price is about 190,000 yen, which is $1,748, 1363 euro. Woo.. I can fly to Brazil again by this price! :)
Another problem is a schedule. Any flight arrives at midnight and departs at noon. 7/8 in or 7/9 in, 7/17 out or 7/18 out. Hmm. When does debconf5 show detailed schedule?
