Non-ticket Revenues. Non-ticket revenues are generated from air travel-related charges for baggage, passenger usage fee
(PUF) for bookings through our distribution channels, advance seat selection, itinerary changes, hotel travel packages and
loyalty programs such as our FREE SPIRIT affinity credit card program and $9 Fare Club. Non-ticket revenues also include
revenues derived from services not directly related to providing transportation such as the sale of advertising to third parties on
our website and on board our aircraft.
Substantially all of our revenues are denominated in U.S. dollars. Passenger revenues are recognized once the related
flight departs. Accordingly, the value of tickets sold in advance of travel is included under our current liabilities as “air traffic
liability,” or ATL, until the related air travel is provided. Non-ticket revenues are generally recognized at the time the ancillary
products are purchased or ancillary services are provided. Non-ticket revenues also include revenues from our subscription-
based $9 Fare Club, which we recognize on a straight-line basis over 12 months. Revenue generated from the FREE SPIRIT
credit card affinity program are recognized in accordance with the criteria as set forth in Accounting Standards Update ASU
No. 2009-13. Please see “—Critical Accounting Policies and Estimates—Frequent Flier Program”.
We recognize revenues net of certain taxes and airport passenger fees, which are collected by us on behalf of airports and
governmental agencies and remitted to the applicable governmental entity or airport on a periodic basis. These taxes and fees
include U.S. federal transportation taxes, federal security charges, airport passenger facility charges and foreign arrival and
departure taxes. These items are collected from customers at the time they purchase their tickets, but are not included in our
revenues. We record a liability upon collection from the customer and relieve the liability when payments are remitted to the
applicable governmental agency or airport.
Our Operating Expenses
Our operating expenses consist of the following line items.
Aircraft Fuel. Aircraft fuel expense is our single largest operating expense. It includes the cost of jet fuel, related federal
taxes, fueling into-plane fees and transportation fees. It also includes realized and unrealized gains and losses arising from any
fuel price hedging activity.
Salaries, Wages and Benefits. Salaries, wages and benefits expense includes the salaries, hourly wages, bonuses and
equity compensation paid to employees for their services, as well as the related expenses associated with employee benefit
plans and employer payroll taxes.
Aircraft Rent. Aircraft rent expense consists of monthly lease rents for aircraft and spare engines under the terms of the
related operating leases and is recognized on a straight-line basis. Aircraft rent expense also includes supplemental rent.
Supplemental rent is made up of maintenance reserves paid or to be paid to aircraft lessors in advance of the performance of
major maintenance activities that are not probable of being reimbursed and lease return condition obligations which we begin
to accrue when they are probable. Aircraft rent expense is net of the amortization of gains and losses on sale and leaseback
transactions on our flight equipment. Presently, all of our aircraft and spare engines are financed under operating leases.
Landing Fees and Other Rents. Landing fees and other rents include both fixed and variable facilities expenses, such as
the fees charged by airports for the use or lease of airport facilities, overfly fees paid to other countries and the monthly rent
paid for our headquarters facility.
Distribution. Distribution expense includes all of our direct costs including the cost of web support, our third-party call
center, travel agent commissions and related GDS fees and credit card transaction fees, associated with the sale of our tickets
and other products and services.
Maintenance, Materials and Repairs. Maintenance, materials and repairs expense includes all parts, materials, repairs and
fees for repairs performed by third-party vendors directly required to maintain our fleet. It excludes direct labor cost related to
our own mechanics, which is included under salaries, wages and benefits. It also excludes the amortization of heavy
maintenance expenses, which we defer under the deferral method of accounting and amortize as a component of depreciation
and amortization expense.
Depreciation and Amortization. Depreciation and amortization expense includes the depreciation of fixed assets we own
and leasehold improvements. It also includes the amortization of heavy maintenance expenses we defer under the deferral
method of accounting for heavy maintenance events and recognize into expense on a straight-line or usage basis until the
earlier of the next estimated heavy maintenance event or the aircraft's return at the end of the lease term.
Loss on Disposal of Assets. Loss on disposal of assets includes the net losses on the disposal of our fixed assets, including
losses on sale and leaseback transactions.
