A young Chicago medical school gradute is travelling to five countries in 30 days with a big mission — to raise money for a school in Zambia that his parents founded for orphaned and abandoned children. Greg Krause, 39, bought a JetBlue All You Can Jet Pass, a promotional offer that allowed 30 days of unlimited flights for $599. He began his jet-setting journey on Sept. 8 in Chicago and will end his trip tomorrow in the same city. During that time he will fly more than 55,000 miles and visit 27 cities in five countries to spread the word about the school.
