The DUB Terminal at Spirit Airlines DUB Terminal provides a straightforward, airline-typical experience. Although it lacks the amenities of more premium carriers, the terminal is functional. The security and check-in procedures are simple, although during busy hours, lines may get very long. It’s best to arrive early because seating is basic and limited. Even though the terminal doesn’t have opulent amenities, it effectively fulfills its function for tourists on a tight budget. If you’re traveling with Spirit, it’s a reasonable option all around, but don’t anticipate luxury.
