Operating Segments and Related Disclosures

We are managed as a single business unit that provides air transportation for passengers and cargo. This allows us to benefit from an integrated revenue pricing and route network that includes American and our wholly-owned and third-party regional carriers that fly under capacity purchase agreements operating as American Eagle. The flight equipment of all these carriers is combined to form one fleet that is deployed through a single route scheduling system. Financial information and annual operational plans and forecasts are prepared and reviewed by the chief operating decision maker at the consolidated level. When making operational decisions, the chief operating decision maker evaluates flight profitability data, which considers aircraft type and route economics, but is indifferent to the results of the individual wholly-owned regional carriers. The objective in making operational decisions is to maximize consolidated financial results, not the individual results of American or American Eagle.

Our operating revenues by geographic region as defined by the U.S. Department of Transportation (DOT) are summarized below (in millions):



	Year Ended December 31,
	2017		2016		2015
DOT Domestic	$	29,612	$	28,620	$	28,761
DOT Latin America	5,422		4,995		5,539
DOT Atlantic	5,059		4,769		5,146
DOT Pacific	2,114		1,796		1,544
Total operating revenues	$	42,207	$	40,180	$	40,990

We attribute operating revenues by geographic region based upon the origin and destination of each flight segment. Our tangible assets consist primarily of flight equipment, which are mobile across geographic markets and, therefore, have not been allocated.
