Unless you travel light, chances are you check your bags when flying. It turns out that the $20 you occasionally pay to check those bags adds up to huge profits for the airlines.

 

In total, 27 airlines took in nearly $1 billion from baggage fees last quarter. That’s a 9-percent increase from the same time last year, according to data released Monday by the U.S. Department of Transportation.
