Priority baggage service professional staff at the Lost & Found and Baggage Claim desk assist customers with missing or lost bags concerns in order to deliver prompt, personal solutions. Real-time flight status is visible on electronic signage throughout the concourse and through the Spirit mobile app. Spirit's customer care team is available landside at ticketing windows and remotely by SMS, WhatsApp, or telephone at  +1-888-839-0502 for modification of reservations and general assistance. Free Wi-Fi covers all areas of public use, while power stations and wireless mobile charging benches help passengers maintain their charge before departure.

Quick-service restaurants, cafes, duty-free shops, hydration stations, and ATMs are some of the dining and retail facilities offered airside.

 Being an ultra-low-cost airline, Spirit Airlines has optimized its services to be centered on efficiency, low costs, and convenience, specifically targeting low-budget travelers. Terminal B at MCO provides a range of services and amenities, most of which are intended to accommodate the high-speed operations of carriers such as Spirit.

Spirit Airlines check-in facilities are found on Level 3 of Terminal B within the North Check-In region. Passengers should report to at least two hours prior to domestic departure and three hours before international flights in order to leave time for security, check-in, and boarding. Spirit Airlines offers a range of check-in methods, which include standard counter check-in, kiosk self-service check-in, and web or mobile check-in through their website or mobile app. Online and mobile check-in are available 24 hours prior to departure and close a hour before the flight, enabling passengers to obtain boarding passes and prepay for bags ahead of time. Self-service kiosks are available throughout the terminal and are frequently used by passengers to minimize lines and check-in more quickly. These kiosks facilitate boarding pass printing and labeling checked baggage, which one can then leave at Spirit-run dedicated bag drop counters.

Spirit Airlines, in line with its ultra-low-cost model, charges separately for most services, including checked and carry-on baggage. Each traveler is allowed one free personal item that fits under the seat, such as a backpack or purse, but carry-on and checked bags come with additional fees, which vary depending on the route and when they are purchased (online in advance vs. at the airport). To make the boarding and baggage more efficient, Spirit invites customers to prepay for a full bag in advance. Spirit agents manning the baggage drop counters are capable of handling baggage problems, weighing and tagging bags, and advising customers about excess or overweight baggage policies. Spirit's strict baggage policies are implemented in order to keep things running efficiently and fairly for everyone, keeping flight boarding on time.

In MCO, Spirit Airlines passengers have security checkpoints near the check-in point in Terminal B and proceed to the gate areas in the Airside 3 concourse. After passing through security, passengers have access to numerous airport facilities. Spirit Airlines occupies gates in Airside 3, which has restaurants, duty-free stores, lounges (though Spirit does not have its own lounge), and charging stations. Spirit does not provide high-end lounges as an ancillary to its low-fare business model, although travelers can still utilize the airport amenities in general and wide cabin seating areas. Family restrooms, changing facilities, and amenities for those with special needs, like elevators, wheel chair assistance, and TTY units, are convenient, so that MCO is friendly to everybody.

Orlando Airport Spirit Terminal flight information is easily available at MCO from several sources. There are overhead electronic flight information displays scattered throughout Terminal B, such as around the check-in counters, baggage claim, and the Airside 3 departure gates. These displays update in real-time with boarding times, gate assignments, delays, and baggage carousel assignments. Spirit's mobile application and website also give real-time flight status information, gate assignments, and estimated departure and arrival times. Travelers are invited to register for flight notifications to receive push notifications, SMS messages, or email notifications with any last-minute flight changes or disruptions.
