Flying in the US usually has less service and higher prices than Europe. It's often cheaper to fly from Europe to the US than within the US. European airlines also started charging for some extras but it's nowhere near the level of the US. Population density is likely the explanation. In Europe most people fly between major city, small cities are often connected by rail to the next airport. That keeps costs low and makes competition easier. In the US there are few direct connections with a lot of demand so that you need to provide a network, increasing barriers of entrance.
