UNITED AIRLINES

U.S. airline, rail and transit systems in New York and other eastern cities initiated sweeping weekend shutdowns and slowdowns on Saturday as Hurricane Irene bore down on the region.

Roger Pielke, a University of Colorado professor and fellow of the Cooperative Institute for Research in Environmental Sciences, warned that Irene is “probably going to be very damaging.”

Airlines canceled nearly 8,000 weekend flights as Hurricane Irene swept up the U.S. east coast toward New York, forcing carriers to move planes to safer areas and halting services at the busiest U.S. hub.

Airlines are now required to clearly post all optional fees on their Web sites, increase compensation for passengers bumped from flights, and provide shorter waiting periods on the tarmac.

Bookings at the carriers are holding their own midway through the third quarter, and a sluggish economy is not materially weakening demand, ATA chief economist John Heimlich told reporters.

United Continental Holdings announced on Sunday that it will spend over $500 million to improve the seats, expand overhead storage, roll out new inflight Wi-Fi and entertainment systems, and renovate older planes - all while creating a consistent costumer experience that combines the most popular offerings of both carriers.
