In 2026, Delta Air Lines utilizes a "Family Seating" algorithm designed to strive to seat children under 13 with at least one adult from their party, but it is not an absolute guarantee for all fare classes. If you purchase Basic Economy, your seats are assigned at the gate, which significantly increases the risk of separation. For those in "Main Cabin" or higher, the system proactively looks for adjacent seats during the booking process. If you find your family is separated on the seat map, Delta's current policy encourages you to contact their "Family Travel" specialists or a gate agent as soon as possible. While they do not "block" entire rows for families like some ultra-low-cost carriers, they frequently hold back specific seats that can be manually assigned by agents to ensure parents are not rows away from their young children, especially following the 2024–2025 DOT push for fee-free family seating.
