To get free seat selection on Delta Airlines, book a Main Cabin fare or higher, as these often include complimentary seat choice. Join Delta's SkyMiles program or reach Medallion Status for additional perks like free preferred seat upgrades. Using a Delta co-branded credit card may also offer seat benefits. Booking early increases the chances of securing preferred seats for free.
