No, babies typically do **not** fly free internationally.
While airlines often allow infants under a certain age (usually under 2 years old) to travel on the lap of an adult for free on *domestic* flights (within the United States, for example), this policy is different for international travel.
According to information from airlines like Delta, for **international travel**, infants traveling on an adult's lap require a **reduced fare**. This isn't a full adult ticket price, but it's also not free.
* **Domestic Travel (e.g., within the U.S.):** Infants under 2 years old often travel free on an adult's lap.
* **International Travel:** Infants under 2 years old traveling on an adult's lap require a reduced fare.
The reduced fare for international infant travel usually consists of:
* Applicable taxes and fees.
* Sometimes a percentage of the adult fare.
Therefore, while significantly less expensive than a full adult ticket or the cost of purchasing a separate seat for the infant, international travel for lap infants is not free. The exact cost varies depending on the airline, the destination, and the specific fare purchased.
