Zero-Dollar Flights: Paradise or Pitfall? 2025 Airline Baby Ticket Prices Compared, Your Complete Guide to Understanding Infant Airfare

Hey everyone, this is Rational Travel, a travel blogger who doesn’t do sponsored content and only tells the truth. If you’re a parent, you know there’s a fleeting golden period in life where you can save serious money: the “infant ticket” era before your kid turns 2. It’s not a long window, but it sure is a battlefield where airlines play mind games and test parents’ intelligence XD.  

This article is written for parents with children under 2 years old.

You probably thought infant tickets were just “10% of adult fare”—simple as that, right? If so, congratulations, you’re about to become the next victim of Thai Lion Air’s shenanigans. Today, Rational Travel is breaking down every airline’s infant ticket rules with crystal clarity, and I’ll tell you which ones are genuinely compassionate and which are masters of linguistic manipulation.

Same old routine—before we dive in, Rational Travel is doing a quick intro, because not everyone knows who I am.

Subscribe to Rational Travel and pocket these strategies

Rational Travel’s honest take: I usually send flight deals and other money-saving hacks to my subscribers first before posting them publicly, so they can grab them early. A lot of these deals have limited time windows and limited inventory, so it only makes sense to give subscribers first dibs.

If you’re used to buying and selling mileage or snagging last-minute hotel deals on Facebook groups, Rational Travel has recently launched ‘platform escrow with pay-after-use‘ on Easy Ticket—now free for subscribers.

P.S. Subscribers get not just complete strategies, but also permanent zero-transaction-fee access to Easy Ticket. It’s free right now, but who knows when I’ll start charging—so you get it. Currently, we have nearly 2,000 subscribers (celebrating with confetti!).
