I just read an article about how much the airline industry makes in extra fees and was mind blowing
We usually fly SouthWest, and take our own snacks on the plane so we rarely pay anything extra, but the few times I've flown other carriers, I'm amazed at all the extras they come up with including paying for headsets, snack packs, ....(and the list goes on)
Snip from article:
Less than half of those fees are paid directly from customers' pockets to the airline. For a typical U.S. airline, about 25% of the revenue comes from baggage fees and 10% come from other a la carte services, such as early boarding and the sales of soft drinks. About 5% comes from package deals, such as hotels, rental cars and insurance programs.
You're paying for that flight one way or another.
