The US Department of Transportation forecasts higher revenues, profits and profit margins for airlines in 2014. The development comes as a result of stable fuel prices, growing demand and route refinements that were possible through several mergers during the recession. To no one’s surprise, 13.5% percent of said increase in revenues comes from reservation change fees. Overall, airlines earned over $3.2 billion in profits during the last quarter. Also to no one’s surprise, loud and unruly children are the number one etiquette violators on planes according to a recent survey. Curiously, the same survey noted that passengers reclining their seats back for the duration of their flights ranked 7th place, even though 80% of passengers admitted to doing the same thing.
