OREANDA-NEWS. UAL announced it would take delivery of 40 new Boeing 737-700 aircraft, which will enter the fleet beginning in mid-2017. These aircraft will replace a portion of the capacity currently operated by the company's regional partners, as the company expects to reduce by more than half the number of 50-seat aircraft in its fleet by 2019.

"Our customers have a preference for an improved travel experience, including first class seats, Economy Plus, and Wi-Fi. These aircraft are an efficient way to meet those needs while reducing 50-seat flying," said Gerry Laderman, UAL's acting chief financial officer.

Participants in the call will include Oscar Munoz, president and CEO; Brett J. Hart, acting CEO; Gerry Laderman, acting chief financial officer; Jim Compton, vice chairman and chief revenue officer; and Greg Hart, executive vice president and chief operations officer.
