Legal Matters and Contingencies [Text Block]	CONTINGENCIES We are subject to certain legal and administrative actions, which we consider routine to our business activities. Management believes that the ultimate outcome of any pending legal matters will not have a material adverse effect on our financial position, liquidity or results of operations. During the third quarter of 2014, the suit filed by the International Brotherhood of Teamsters ("IBT") against the Company and Frontier seeking to have the restructuring agreement declared null and void, or alternatively, seeking that the IBT manage the equity investment of the Frontier pilots due to accusations that the Company interfered with the election process was dismissed. The dismissal arose after the Frontier Airlines Pilots Association ("FAPA") was certified to replace the IBT as the collective bargaining representative of the Frontier pilots. After that occurred, the Company and Frontier sought to have the case dismissed on the ground that the IBT no longer had standing to represent the interests of the Frontier pilots. The IBT then moved to have FAPA substituted as the party in interest. The court granted that motion, after which FAPA indicated that it did not intend to continue to prosecute the case, leading to the dismissal. As of December 31, 2014, approximately 71% of the Company's workforce is employed under union contracts. The union contracts for our pilots is currently amendable. Although we have never had a work interruption or stoppage, we are subject to risks of work interruption or stoppage and/or may incur additional administrative expenses associated with union representation of our employees. If we are unable to reach agreement with any of our unionized work groups on the amended terms of their collective bargaining agreements, we may be subject to work interruptions and/or stoppages. Any sustained work stoppages could adversely affect our ability to fulfill our obligations under our fixed-fee and pro-rate agreements and could have a material adverse effect on our financial condition and results of operations. The Company is currently in a labor dispute with the International Brotherhood of Teamsters ("IBT") Local 357, which represents all of our pilots. On April 4, 2014, the Company announced that members of the IBT Local 357 failed to ratify a proposed four-year pilot labor agreement, which would have increased pay, improved work rules and allotted a significant signing bonus to our pilots. Our inability to pay our pilots, especially our new hire first officers, market level wages is negatively impacting our ability to hire qualified pilots and operate the number of aircraft our Partners desire for us to fly under fixed-fee agreements. In 2014, we did not renew agreements to operate 27 ERJ aircraft and permanently parked 15 E140 aircraft, temporarily parked 12 E145 aircraft and temporarily parked an operational spare. The Company may need to park additional ERJ aircraft in 2015 and 2016 as a result of the current labor dispute, which could cause us to fail to meet the required performance levels under our CPAs.
