How Delta seat selection works by fare, extra legroom options, upgrade routes, and the family seating rules that let children sit with a parent free.
Key Travel Facts & Insights
Free advance seat selection on Main Cabin and above. Basic Economy tickets are assigned a seat automatically at check-in and cannot choose in advance, though you are still seated in the Main Cabin.
Delta Comfort+ adds up to 3 inches of pitch plus dedicated bin space. Preferred Seats are standard-pitch Main Cabin seats further forward, sold at a smaller premium.
Medallion members receive complimentary upgrades on a rolling window by tier, with Diamond clearing first at 120 hours. Everyone else can buy an upgrade at booking, at check-in, or bid where offered.
Delta seats children 13 and under adjacent to an accompanying adult at no additional cost, in line with the US Department of Transportation family seating commitment. Book on the same reservation for the system to apply this automatically.
