Yes, you can choose your seat on a Delta flight, although the options may vary based on your ticket type and when you book. During the booking process, Delta allows passengers to select seats for most fare types, including Main Cabin, Comfort+, and First Class. If you purchased a Basic Economy ticket, however, you may not be able to choose a seat in advance, and one will be assigned to you during check-in. For those wanting extra comfort or specific seating preferences, Delta also offers paid seat upgrades. It's best to book early for the widest selection.
