Airlines and hotels have been loading on junk/crap fees, and then increasing them for nearly 10 years minimum. The airlines started after the near meltdown of their industry post 9/11 and the subsequent bankruptcies many of them went through. That was followed up by the fuel surcharges to offset unhedged fuel costs. When the price of jet fuel came down, the fuel surcharges morphed into misc. fees. Then they unbundled various services from the fares and started charging extra for those too. It's a beautiful thing when the free market economy gets twisted around like this.
For hotels, it's been the resort fee. They bundled up a collection of things, made them mandatory (unless you have a certain level of elite status with some hotels) and get away with advertising what is often a deceptively low rate per night. Add-on parking fees, early check in fees, early check out fees, metered drinks for VP at a bar and a host of other fees and surcharges and, once again, the customer gets less value for every dollar forked over.
I've lived through a few economic downturns and there'll be another one sometime soon. I can hardly wait.
