Big profits expected for US airlines in robust 2011 but fuel prices loom

US airlines will report USD3.95 billion in profits on USD122.2 billion revenue for 2010, according to AirlineFinancials.com founder Bob Herbst, who issued his expectations over the weekend. However, he expects the average profit margin to be 3.3%, well below the targets of the eight largest US airlines tallied but within their historical norms.
