Delta Airlines Seat Selection lets passengers choose their preferred seat during booking, at check-in, or anytime in between via delta or the Fly Delta app. Standard Main Cabin seats are typically free to select, while Preferred and Comfort+ seats carry an added fee based on route and seat location. Basic Economy fares don't allow advance selection — seats are assigned automatically at check-in. Premium cabins like Delta One, First Class, and Premium Select generally include complimentary seat selection. SkyMiles Medallion members often get free access to upgraded seating as an elite benefit.
