Spirit Airlines FLL Terminal is based at Fort Lauderdale-Hollywood International Airport (FLL) Terminal 4, where it offers passengers the necessary facilities for a smooth travel experience. Ticket purchase, upgrade, and alteration are attended to by the ticket counters, while there are several self-service machines that enable efficient and speedy check-in. Baggage services are provided at specific counters that cater to check-in, drop-offs, claims, and retrieval of lost items. Flight information screens are placed all over the terminal, providing real-time information on departures and arrivals. Spirit's own customer care team is available to help passengers both physically and virtually through text messaging and WhatsApp services. Terminal 4 is built for convenience with accessible facilities such as charging points, seating lounges, and food and beverage outlets for a pleasant wait.

The area for tickets is large, with several self-service kiosks for those who would like to check in themselves or buy last-minute tickets. Technology use is encouraged by Spirit Airlines to reduce wait times; hence, self-service kiosks are strongly promoted. For those passengers who need more help, Spirit has special ticket counters attended by Spirit Airlines agents who can assist in the purchase of tickets, changes to reservations, special service needs, and payment of baggage or upgrade fees.

The check-in procedure at the Spirit Airlines terminal is simple but important to handle with care because of the airline's strict timing regulations. Passengers are advised to report at least two hours prior to their departure time to allow sufficient time to finish check-in and security processes. There are exclusive lines for online check-in and bag drop, which assists in accelerating the process for remote check-in passengers. Regular check-in counters are also there for those who prefer assistance in person, like families with young children, special needs passengers, or those whose itineraries are complex.

Baggage handling at the Spirit Airlines FLL Terminal is complete, in spite of the airline's fame for bare essentials. Well-defined zones close to the ticket counters enable the payment for and checking of baggage. Spirit Airlines is a fee-for-service operation, and therefore passengers have to prepay or pay at the counter for carry-on and checked bags as well. The agents help weigh bags, tag them correctly, and guide passengers to the proper drop-off locations. For oversized or specialty items, like sporting goods or musical instruments, extra services are offered, although passengers are highly recommended to check Spirit's baggage policies online before reaching the airport to prevent surprise fees.

Flight details are easily available throughout the Spirit Terminal Fort Lauderdale area of Terminal 4. Large, clear digital screens show minute-by-minute information about arrivals, departures, delays, and gate assignments. These screens are placed strategically above ticket counters, security checkpoints, and boarding gates, keeping travelers well-informed at each stage of their journey. Spirit Airlines also encourages customers to use their mobile application, which delivers real-time notifications, gate assignments, and boarding updates to customers' mobile devices, a necessity since the airline has made a big push into self-service and digital interaction.

Customer service at the FLL Spirit Terminal is meant to be convenient but streamlined, consistent with the carrier's low-cost business model. Customer service areas are found in the ticketing area as well as outside security at the gates, where agents handle flight-related questions, rebooking because of delays or cancellations, and lost luggage reporting.
