The City of Angels is expected to have quite the hellish airport this Thanksgiving holiday. According to an annual ranking by Orbitz, LAX will top Chicago's O'Hare International Airport as the nation's busiest this holiday weekend, from Nov. 23 to Nov. 27. Filling out the top five (in order) are Orlando International, San Francisco International, and Boston's Logan International airports. Orbitz calculates its ranking by adding up tickets sales for the country's 50 major airports, the Los Angeles Times reports. (More Thanksgiving travel stories.)
