Frontier's boarding process begins with boarding passengers who need extra assistance first, followed by myFRONTIER Miles elite members and people who have purchased priority boarding. Then they allow families to board, and finally the rest of the passengers through general boarding.

Yes, Frontier Airlines provides a specific "Family Boarding" window during the boarding process. In 2026, this occurs directly after Group 1 and before Group 2. It is specifically available for families traveling with children under the age of 2. For families with older children, Frontier relies on its "boarding zones" based on seat selection and elite status; however, the airline has recently made strides in family-friendly policies by guaranteeing that at least one adult can sit next to children under 14 at no extra cost, provided they are on the same reservation. If you are not in the "under 2" category, you will board with your assigned group, but Frontier Miles elite members (Silver, Gold, and Platinum) and those who purchase "Board First" or "Premium" bundles will often find themselves in earlier groups, making it easier to settle in with the "flock" before the plane fills up.
