44 Flight Booking Myths That Are Actually Wasting You Money

Myth 28: Children Always Fly Free or Cheap

Many parents assume flying with young kids is inexpensive, but that’s not always the case—especially once children age out of lap-infant status. While infants under two years old can often fly for free domestically when seated on a parent’s lap, that doesn’t apply to international travel, where taxes and fees still apply—sometimes totaling hundreds of dollars. And once a child turns two, they legally require their own seat at full price, even on budget carriers. Airlines rarely offer discounts for kids over age two, and in some cases, families may be forced to pay more to ensure seats together. Plus, ancillary fees (like checked bags, early boarding, or snacks) can quickly add up when traveling with a child. The key is to always price out each traveler individually and look into family booking options or fare bundles that may include perks like priority seating or extra baggage. Never assume a discount—because what sounds like a budget-friendly family trip can quickly balloon into a costly experience if you’re unprepared.
