o In May 2014, SkyWest announced Russell “Chip” Childs as President, SkyWest, Wade Steel EVP, SkyWest and Michael Thompson, COO, SkyWest Airlines
o In the second half of 2014, SkyWest expects 56 of its unprofitable 50-seat aircraft contracts will naturally expire and the aircraft will be returned to lessors. SkyWest also expects an additional 101 unprofitable 50-seat aircraft contracts will naturally expire and be removed from service by December 31, 2015.
o SkyWest added eight E175 regional jet aircraft as of June 30, 2014, expects delivery of 13 additional E175 aircraft by December 31, 2014 and the remaining 19 additional aircraft by August 2015. With the training and other start-up costs associated with the E175 aircraft launch, SkyWest anticipates the economic benefit of the E175 aircraft will become evident by the second quarter of 2015.
o SkyWest invested approximately $26.8 million for E175 specific spare parts, engines and tooling as of June 30, 2014 and anticipates investing another $10.0-$12.0 million for similar items by the end of 2014. SkyWest also invested $33.6 million into E175 ownership equity as of June 30, 2014.
