If you’re planning a special trip with your grandbaby, you may be wondering: “How do I add a lap infant to my Delta flight?” The good news is, it’s simpler than you might think. Delta allows children under 2 years old to travel as lap infants — and in many cases, domestic flights don’t cost extra.
For seniors who prefer a little extra help, calling 877-297-0699 can be the easiest way to make sure everything is handled correctly. In this guide, we’ll break down what you need to know step by step.
A “lap infant” is any child under 2 who will sit on an adult’s lap during the flight. On most domestic Delta flights, lap infants fly for free, while international flights may require a small fee or taxes.
Good to know: The FAA permits lap infants, but the American Academy of Pediatrics recommends a car seat for maximum safety. Seniors can weigh comfort vs. safety depending on the length of travel.
