THEREFORE the parties to this Letter of Agreement hereby agree as follows:

Except for the code sharing pursuant to the Code Share Agreements expressly permitted under this Letter of Agreement, all provisions of Section 1 of the Pilot Agreement shall remain in full force and effect.
2. System Flying. The Company shall measure and report the total number of mainline available seat miles (“ASMs”) scheduled to be operated by US Airways each month under the UA Code. The Company shall not permit the number of mainline ASMs scheduled to be operated by US Airways under the UA Code to exceed 41% of the mainline ASMs operated by the Company in any rolling twelve-month period.

5. USX Flying.
a. The Company shall only permit the UA Code to be used on the following USX Carrier flights:
i. any flights to or from PIT, PHL or CLT provided that (x) no such flights shall stop at DEN, LAX or SFO and

any such flights that stop at ORD or IAD shall be point-to-point flights from PIT, PHL or CLT and shall not be operated on jet aircraft with a maximum certificated seating capacity in excess of 50 seats;
ii. flights to or from BOS or MIA provided that such flights may not be operated on jet aircraft with a maximum certificated seating capacity in excess of 50 seats, at least 90% of such flights may not exceed 850 nautical miles, and none of such flights stop at IAD, ORD, DEN, SFO or LAX;
iii. flights to or from LGA, EWR and JFK (collectively, “NYC”) provided that (x) such flights may not be operated on jet aircraft operated with a maximum certificated seating capacity in excess of 50 seats, at least 90% of such flights may not exceed 850 nautical miles, and no such flights stop at IAD, ORD, DEN, SFO or LAX, and

the Company shall not permit the number of ASMs operated by US Airways and USX Carriers to or from NYC under the UA Code to exceed 28.1% of the ASMs operated by the Company to or from NYC; and
iv. flights to or from DCA and BWI provided that (x) such flights may not be operated on jet aircraft operated with a maximum certificated seating capacity in excess of 50 seats, at least 90% of such flights may not exceed 850 nautical miles, and no such flights stop at IAD, ORD, DEN, SFO or LAX, and

the Company shall not permit the number of ASMs operated by US Airways and USX Carriers to or from IAD, DCA and BWI (collectively “WAS”) under the UA Code to exceed 21.1% of the ASMs operated by the Company to or from WAS.
b. The Company shall hold each USX Carrier that operates flights under the UA Code to the same safety, operational performance and passenger service standards imposed on United Express carriers (including the annual safety audits of such USX Carriers performed by the Company).
6. Reciprocal Code Share Arrangements.
a. The Company shall make commercially reasonable efforts to place the US Code on all of the ASMs operated by the Company within twelve (12) months of the effective date of this Letter of Agreement (the “Phase-In Period”), except to the extent the Company (i) fails to receive required government approval for code sharing on flights despite its best and continuing efforts to obtain such approval; or (ii) is prohibited by the collective bargaining agreement(s) between the Company, US Airways and/or USX Carriers and any of their unions in effect as of the effective date of this Letter of Agreement and (iii) the airport facility, airport authority, or other physical restrictions on airport locations make such implementation impossible or unreasonably expensive in relation to the benefit of the code share at such location.
b. If, after the conclusion of the Phase-In Period, the Company fails to place the US Code on 100% (minus the exclusions provided for in paragraph 6.a above) of the Company ASMs, in any scheduling month, then, for the next scheduling month, the Company shall limit the number of US Airways ASMs operated with the UA Code to a percentage of US Airways ASMs calculated as 105% minus [100% *(A-B) / A], where A is the number of UA ASMs that should have been operated under the US Code and B is the number of UA ASMs actually operated under the US Code. For example, if the Company was required to operate 16 billion ASMs under the US Code in a given month but only operated 14 billion under the US Code during the month, the Company would be required to limit the UA Code to 92.5% of US Airways ASMs –[105% minus (100%*(16-14)/16]. For the purposes of all calculations in this paragraph, all ASMs for both carriers will be net of exclusions in paragraph 6.a. above.
7. Block Space Arrangements. The Company shall be prohibited from entering into any block space arrangements (i.e., the advance purchase or reservation of blocks of seats on other carriers for resale by the Company) with US Airways or any USX Carrier.
