FORT WORTH, Texas _ After years of embracing the carry-on, airline passengers have begun checking baggage at a dramatically increased rate in recent days, spurred by new security rules barring most liquids and gels in airplane cabins.

Twenty years ago, a Delta Airlines jumbo jet was approaching the Dallas-Fort Worth airport when the crew noticed an ordinary summer thunderstorm in their path. The captain mentioned it to his co- pilot, but there was no indication that the crew was concerned.

ATLANTA - Delta Air Lines will cut up to 7,000 jobs, or 10 percent of its overall work force, cut wages and pull back at its Dallas-Fort Worth airport hub as part of a sweeping restructuring plan that could still leave it vulnerable to needing to file for bankruptcy, company CEO Gerald Grinstein said Wednesday.
