When making a reservation, travellers can select the seats they want with Delta Seat Selection policy; the selections vary depending on the type of fare. Main Cabin, Comfort+, and Premium cabins offer more freedom than Basic Economy prices, which frequently offer little or no seat option. Using the Delta app or website, passengers can choose their seats at the time of booking or modify their selections at a later time. Delta's customer service can help with seating arrangements if you have any special needs or preferences.
