Internationally, the torch and its accompanying party traveled in a chartered Air China Airbus A330 (registered B-6075), painted in the red and yellow colors of the Olympic Games. Air China was chosen by the Beijing Committees of the Olympic Game as the designated Olympic torch carrier in March 2008 for its long-standing participation in the Olympic cause. The plane traveled a total of 137,000 km (85,000 mi) for a duration of 130 days through 21 countries and regions.
If it is possible to answer this question, answer it for me (else, reply "unanswerable"): How many days did the plane travel?
130 days
