United cancels some Hawaii flights due to Maui wildfires; Alaska Air flags delays

United Airlines Holdings said Thursday that it had canceled flights to Kahului Airport in Hawaii's Maui and would fly empty planes to the wildfire-hit island to bring passengers back to the mainland. Separately, Alaska Air Group flagged some delays because of the wildfires earlier in the day, but said that it was sticking to its regular flight schedule from Maui. Alaska Air is also adding an extra flight to facilitate rescue efforts and may consider including more depending on the situation, it said. "In terms of operational impact, we are delaying some flights to ensure smooth operations," the carrier said.<br/>
