"During the holiday rush, millions of tired travelers pass through Toronto Pearson Airport. Toronto Pearson asked us to come up with an initiative to make traveling at this crazy time a little more enjoyable. Friends and family were asked to go to the Toronto Pearson Airport Twitter page and tweet the name and flight number of friends and families who were traveling over the holidays. Carolers then met them and sang to them a personalized holiday carol. It was called Tweet a Carol."
