Great Lakes will be utilizing interline a-ticketing and baggage agreements with American 

Airlines, Delta Airlines, Frontier Airlines, United Airlines and U.S. Airways. All of which will offer 

passengers maxium access to the domestic and international air transportation system at the 

Minneapolis hub. 

Great Lakes and Delta Airlines are coordinating an upgrade of electronic communication 

systems to enable Great Lakes to provide Delta boarding passes and Sky Miles processing. 

Delta and Great Lakes also intend to enable the sale of Great Lakes' passenger segments on 

the Delta website for added passenger convenience. These reservation system upgrades are 

anticipated to be completed in the Spring of 2012.
