This document contains Great Lakes Aviation, Ltd.'s response to Order Requesting 

Proposals 2014-12-2. 

Great Lakes Aviation, Ltd. is pleased to submit this proposal to provide essential air 

transportation at El Centro/Imperial, California. The attached proposal contemplates the use of 

pressurized 30 seat Embraer EMB-120 Brasilia aircraft. Great Lakes has been operating the 

Brasilia since 1994 and beleives it it well suited to serve the market. 

The Company has been developing a Los Angeles (LAX) hub for the last several years and 

utilizes gate facilities in Terminal 6. With security screeening accomplished at the El CentroImperial airport, passengers will conveniently connect to American, Delta and United without 

being required to visit a LAX checkin counter or passenger security processes.

agreements American, Delta and United. Customers will also be eligible for Delta Sky Miles 

Frequent Flyer program when travel is booked through Delta's sales channels. All of which will
