Even if you do watch what you eat this Thanksgiving, expect things to get tight in the cabin on your holiday flights.
On the busiest travel days around Thanksgiving, the average flight is expected to be 90% full, according to Airlines for America, the trade group for the nation's largest airlines.
Flights will be especially crowded on Nov. 21, the day before Thanksgiving, and on Nov. 25 and 26, the Sunday and Monday after Thanksgiving, according to the trade group.
In contrast, the average flight in 2011 was 82% full, according to federal statistics. The rate of filled seats on planes, known as the "load factor," has been on the rise over the last few years as airlines have merged, cut less-profitable routes and consolidated flights on popular routes.
