1.2           Industry procedures set forth in the ATA Resolution 5.65 (Interline Traffic Agreement - Passenger) for carriage solely within and between the United States and Canada and any existing agreements between Delta and Big Sky relating to the interlining of passengers and baggage shall apply to the provision of air transport and the related transactions contemplated by this Agreement, except to the extent inconsistent or in conflict with the terms of this Agreement.

2.1           Subject to the receipt of all required approvals from all applicable Competent Authorities, commencing on the date of completion of the implementation development described in Section 3 hereof (but no later than April 8, 2007) (the “Effective Date”) Delta shall place its two letter flight designator code (“DL”) on select flights operated by Big Sky (“Hosted Prorated Flights”) to/from Boston Logan International Airport (“BOS”) as identified in Annex B and connecting (as determined by standard CRS criteria and minimum connect times determined by the parties) to or from a Delta operated service.  The parties shall mutually amend Annex B attached hereto and incorporated herein by this reference from time to time during the term of this Agreement to add and remove such flights as Hosted Prorate Flights covered by this Agreement; provided, however, that Delta may remove the “DL” code from any specific Hosted Prorate Flight upon sixty (60) days prior written notice to Big Sky.  Except as provided otherwise in this Agreement, the parties acknowledge that the rights of Delta to remove the “DL” code specified in the immediately preceding sentences relates only to the removal of the “DL” code from specific flights and is not intended to provide Delta with an

1

opportunity to remove its code from all flights covered hereby.  The schedule planning of Hosted Prorate Flights shall be done in coordination with Delta.

2.2           Detailed procedures mutually agreed upon by the parties for implementing this Agreement will be set forth in a procedures manual to be prepared by the parties in conjunction with this Agreement (the “Procedures Manual”).  The Procedures Manual, including any amendments or supplements thereto agreed in writing between the parties from time to time, is incorporated by reference into and made a part of this Agreement; provided, however, that in the event of a conflict between a provision of this Agreement and any provision of the Procedures Manual, as amended and supplemented, the terms of this Agreement shall prevail.

2.3           In the event of any flight delay or cancellation of a Hosted Prorate Flight (other than due to weather related causes) that requires a Codeshared Passenger to be involuntarily rerouted or denied boarding and denied boarding compensation is paid to such passenger, Big Sky shall bear all associated costs arising out of such involuntarily rerouting or denied boarding. If the delay or cancellation is due to weather and Big Sky is unable to reroute passengers to their final destination, the passengers will be responsible for all ground costs and expenses incurred by them, including, without limitation ground transportation, accommodations, and meals.  Big Sky shall do all possible to assist with obtaining a hotel and possibly a special “distressed” rate for those passengers.

2.8           Big Sky intends to perform the Hosted Prorate Flights using Beechcraft 1900D aircraft and related equipment under its own technical and operational control.  Subcontracting

2

of such services by Big Sky to a third party is not permitted without the prior written consent of Delta, and Delta is not obligated to agree to place its code on subcontracted flights.  The responsibility and liability of Big Sky under the terms of this Agreement (including insurance and indemnity obligations) shall not be affected by any such subcontracting.

2.9           The Parties recognize that operational safety is of paramount importance to the provision of codesharing under this Agreement.  In the event that Delta has reasonable grounds to be concerned about safety issues relating to the operation of Hosted Prorate Flights, Delta shall have the right immediately to (a) suspend codesharing on Big Sky’s flights and (b) reaccommodate its passengers on Delta-operated flights or flights of other air carriers.  If Delta reaccommodates its passengers in accordance with this Section 2.9, Big Sky shall reimburse Delta for all costs and expenses incurred by Delta in connection with all such reaccomodations.
