Note B — Passenger and Ground Handling Revenue

The Company recognizes passenger and ground handling revenues when the service is provided under its code-share agreements. Ground handling revenue primarily consists of customer service functions such as gate and ramp agent services at applicable airports where the Company provides such services to other airlines. Under the Company’s fixed-fee arrangements (referred to as “fixed-fee arrangements, “contract flying” or “capacity purchase agreements”) with Delta Airlines Inc. (“Delta”), United Airlines Inc. (“United”), US Airways Group, Inc. (“US Airways”), American Airlines, Inc. (“American”) and Alaska Airlines, Inc. (“Alaska”), the major airline generally pays the Company a fixed-fee for each departure, flight or block time incurred, and an amount per aircraft in service each month with additional incentives based on flight completion and on-time performance. The major airline partner also directly reimburses the Company for certain direct expenses incurred under the fixed-fee arrangement, such as fuel expense and landing fee expenses. Under the fixed-fee arrangements, revenue is earned when each flight is completed.

Under the Company’s revenue-sharing arrangements (referred to as “revenue-sharing” or “pro-rate” arrangements), the major airline and the Company negotiate a passenger fare proration formula when a passenger has a connecting flight operated by both the Company and the major airline partner, pursuant to which the Company receives a percentage of the ticket revenues for those passengers traveling for the portion of their trip operated by the Company, and the major airline retains the ticket revenues for the other portion of their trip on the major airline. Revenue is recognized under the Company’s pro-rate flying agreements when each flight is completed based upon the portion of the pro-rate passenger fare the Company anticipates that it will receive for each completed flight.

Other ancillary revenues commonly associated with airlines such as baggage fee revenue, ticket change fee revenue and the marketing component of the sale of mileage credits are retained by the Company’s major airline partners on flights that the Company operates under its code-share agreements.

In the event that the contractual rates under the Company’s flying agreements have not been finalized at quarterly or annual financial statement dates, the Company records revenues based on the lower of the prior period’s approved rates, as adjusted to reflect any contract negotiations, and the Company’s estimate of rates that will be implemented in accordance with revenue recognition guidelines. In the event the Company has a reimbursement dispute with a major partner, the Company evaluates the dispute under its established revenue recognition criteria and, provided the revenue recognition criteria have been met, the Company recognizes revenue based on management’s estimate of the resolution of the dispute.

In several of the Company’s agreements, the Company is eligible to receive incentive compensation upon the achievement of certain performance criteria. The incentives are defined in the agreements and are measured and determined on a monthly, quarterly or semi-annual basis. At the end of each period during the term of an agreement, the Company calculates the incentives achieved during that period and recognizes revenue attributable to that agreement accordingly.

The following table summarizes the significant provisions of each code share agreement the Company has with each major partner:

Other Revenue Items

The Company’s passenger and ground handling revenues could be impacted by a number of factors, including changes to the Company’s code-share agreements with its major partners, contract modifications resulting from contract re-negotiations, the Company’s ability to earn incentive payments contemplated under the Company’s code-share agreements and settlement of reimbursement disputes with the Company’s major partners.
