News Release

GAAP To Non-GAAP Reconciliations

Pursuant to SEC Regulation G, the Company has included the following reconciliation of reported non-GAAP financial measures to comparable financial measures reported on a GAAP basis. Since the Company did not apply cash flow hedge accounting prior to April 1, 2010, the Company believes that the net fuel hedge adjustments provide management and investors with a better perspective of its performance and comparison to its peers because the adjustments reflect the economic fuel cost during the periods presented and many of our peers apply cash flow hedge accounting. The non-cash mark-to-market gain/loss adjustment includes the reversal of prior period non-cash mark-to-market gain/loss related to August hedge settlements.

	August 2010
Mainline fuel price per gallon excluding non-cash, net mark-to-market gains and losses	$	2.38
Add: Non-cash, net mark-to-market (gains) and losses per gallon		0.03
Mainline fuel price per gallon	$	2.41
