There was very heavy traffic around the airport at the time .The driver was going to drive them to the university instead .The driver wanted them to miss their flight .None of the above choices .
Why may the shuttle have been late ?
Then I had met another guy who was going to the same university in the flight . So we went around the houston airport for a while , as our ground shuttle was supposed to pick us up at 9:30 pm . The shuttle arrived at the airport around half an hour late .
