USA New Orleans airport remains closed By Gay Nagle Myers / August 30, 2012 Share 1 -- Louis Armstrong Airport in New Orleans remained closed to all flights Thursday. The airport lost power and is operating on generators. The airport will reopen when power is restored. About 60% of businesses and homes in New Orleans were without power on Thursday, as well. Attractions will reopen as soon as possible, depending on weather and power outages, according to the New Orleans Convention & Visitors Bureau. This weekend's Southern Decadence Festival, an annual event that usually draws more than 100,000 people, is expected to take place as planned. Activities center around a dozen bars in the French Quarter and nearby neighborhoods and include a parade on Sunday. Further east, Mississippi gaming officials hope to reopen the state's 12 casinos along the coast once portions of Interstate 90 that front the casinos reopen. Floodwater forced closure of sections of the highway. None of the casinos reportedly sustained structural damage. L'Auberge Casino and Hotel in Baton Rouge, La., canceled its soft opening planned this week. Delta canceled its flights into Shreveport, La., until Friday morning. United and American were running normal schedules into Shreveport on Thursday. Follow Gay Nagle Myers on Twitter @gnmtravelweekly.
