Delta airline users can select or change their seats while booking, during check-in, or in the "My Trips" section. In case a seat is labelled as occupied, it means that it has already been selected by another passenger. Delta airlines seat selection offers various seat options, including Main Cabin, Delta Comfort+, First Class/Business, Delta Premium Select, and Delta One Suites[2]. Users can choose an available seat that suits their preferences and travel companions, and some seats provide additional space, such as the preferred seats.
