Some major airline carriers have canceled flights to the New Orleans and Gulfport, Mississippi airports for at least next week.
The cancellations to the popular sites for tourists, conventioneers and gamblers puts increased financial pressure on airlines as they also deal with potential fuel shortages.
Jack Evans, of the Air Transport Association, says daily jet fuel production nationwide has been cut 13 percent because of damage from the hurricane to Gulf Coast refineries.
Atlanta-based Delta Air Lines, the nation's third-largest carrier, has canceled all flights into and out of the New Orleans and Gulfport airports through Monday.
As for fuel, a spokesman says Delta is working closely with suppliers to make sure contingency plans are in place to deal with any potential shortages.
The nation's larges carrier, American Airlines, canceled 34 flights in and out of New Orleans Wednesday. Spokesman Tim Smith says the Fort Worth, Texas-based carrier doesn't expect to resume scheduled flights there until next Tuesday at the earliest.
The New Orleans airport has reopened to allow humanitarian flights in and out during daylight hours. But officials are unsure when commercial service will resume there.
