Do airlines want us to suffer? Travel guidelines advise showing up hours early to check-in for flights that are delayed 20 percent of the time. Before boarding, there are often hundreds of dollars in possible fees: $25 for the first bag, $15 to board first, $16 for Wi-Fi, $59 to boost frequent flier miles, and more for oversized luggage, slightly better economy seats, or an itinerary change. But there are better ways. Instead of handing that money to the airlines, why not give it to a business that offers competitive rates and gives you something back? Here are four apps that think the misery inherent in airline travel can be avoided, and your cash can be put to better use.
