EXST® pertains to which special service option?

The designation EXST® specifically refers to the provision of an extra seat reservation. This service is intended for passengers who may require additional space during their flight, such as those who may feel more comfortable with two seats for personal or medical reasons. By allowing the reservation of an extra seat, airlines ensure a more accommodating experience for individuals who need or prefer this option.

The other choices pertain to different services. Fast track services are meant to expedite security or check-in processes, family fare options generally offer discounted rates or packages for families traveling together, and bulk sports item requests involve special accommodations or fees for transporting larger sports equipment. Each of these options serves a different customer need, which illustrates the diversity of special service requests available to enhance passenger satisfaction.
