Seat selection fees
: Whether you want a window seat or want to sit together as a family, you may have to pay extra for that choice. "While some budget airlines like Norwegian have been charging passengers more than $40 to choose their seats, as of December 2018, major United States carriers like Delta, American, and United were charging for seat selection for preferred seats; costs started at $9 per passenger," Zillmer explains.
: Most people know that for the majority of airlines, checked bags cost extra. But Zillmer warns, "Some airlines are introducing new classes like 'basic economy,' providing passengers with the option to pay less for a flight ticket if they forgo having a carry-on." He recommends doing your research ahead of time (as baggage fees and size requirements vary from airline to airline) and weighing your bags before you head to the airport to avoid oversized luggage charges.

Food and drink fees
: While longer flights are often required to provide a free meal, don't assume that drinks and snacks will be complimentary. Zillmer advises passengers to purchase food or beverages in the airport before you board as in-flight prices are often more expensive. Just remember not to buy your beverages until you get through security.
: How and where you buy your airfare could actually affect the price. Booking online is typically free; however, many airlines charge a convenience fee for flights purchased over the phone or in person.
