Katie Holmes and Suri Cruise walked through an NYC airport today to take a flight out of town. The girls are getting used to flying commercial, after years of living it up in private jets traveling with Suri's dad, Tom Cruise. Of course, once in a while, they both still travel in smaller, exclusive planes. Suri's racked up the frequent flier miles recently, traveling from Katie's new home base in the Big Apple out to visit with Tom in the Hamptons and even at Disney in Florida. All the travel will have to cease for a bit once Suri starts her first day of school. According to a new report, Tom and Katie will both drop Suri off on her first day of kindergarten after Labor Day.
