How to Use the Traveling with Kids Extra Cost Calculator
Traveling with children comes with discounts on flights and admission tickets, but also unexpected extras like hotel bed fees. This calculator takes your child's age, number of kids, adult flight and admission prices, and nights of stay, then applies age-based discount tiers to show exactly how much more the trip will cost.
Infants under 2 fly on a lap infant fare that's dramatically cheaper and are usually admitted free to attractions. Children between 2 and 11 typically get around 75% of the adult flight fare and half-price admission, and almost always need an extra bed at hotels. Kids 12 and older are generally charged the full adult rate.
Actual discount rates and bed fees vary by airline, hotel, and venue, so treat this result as a planning estimate and confirm the exact policy before you book.
Frequently Asked Questions
