@abc7chicago: As the Thanksgiving weekend wraps up, Sunday is expected to be one of the busiest travel days of the year. Both O'Hare and Midway airports are expecting to see 2 million people pass through this holiday weekend. Millions of Americans are making their way home and some wintry severe weather in parts of the country is making that trip home even more challenging. In fact, AAA said air travelers will set a record with nearly 6 million flying domestically.
