Lost Luggage:

Even though almost all of the airlines charge baggage fees now, that doesn't mean they're doing any better at actually making sure you and your luggage arrive in the same place at the same time. In fact they're getting worse. The data is in from 2010 and lost luggage went up 6% from 2009. Worldwide, airlines lost 29.4 million bags plenty of which people paid $25 and up to check. That's the equivalent of 12 mishandled bags for every 1,000 passengers or, they lost the equivalent of one bag for every person in Texas and Kentucky combined. (ABC News)
