Delta Air Sees 4Q Profit As Sector Rallies
2010-10-21 01:34:00 The head of Delta Air Lines Inc. (DAL) said Wednesday that the European Union should help the region's carriers compete with fast-growing Middle East rivals. Richard Anderson, Delta's chairman and chief executive officer, is the first U.S. airline executive to address the competitive threat of carriers such as Emirates, Etihad and Qatar Airways, which are using their geographical position to take market share from established entrants on long haul international routes. European carriers including Deutsche Lufthansa AG (DLAKY, LHA.XE) and Air France-KLM (AFLYY, AF.FR)--a Delta partner in the SkyTeam alliance--have rallied against Middle East rivals, alleging they receive unfair subsidies. Emirates and others deny the charge. Anderson said on a conference call that the European Union should support airlines in the region by providing antitrust immunity for services to Asia. SkyTeam and the other two global alliances--Star and Oneworld--have benefited from immunity to cooperate on tr...

Lolla '09 review: Delta Spirit
2009-08-08 21:34:00 12:30 p.m. Budweiser stageA sunny day band all the way, San Diego quintet Delta Spirit has an awful lot of soul for a band that doesn't play soul music, with the group's jangly, piano-spiked rock often becoming a cathartic experience. The band didn't build a ton of momentum through their hour-long set, but the defiant stomp of "People C'Mon" made toe-tappers ask for mercy, while the heartfelt plea of closer "People, Turn Around" is the sort that makes old friends want to forgive each other.Find tons of reviews, photos and more in our complete Lollapalooza guide...
