By David ShepardsonWASHINGTON (Reuters) - The U.S. Transportation Security Administration said it had screened 2.99 million airline passengers on Sunday, the highest-ever number in a single day. A group representing major U.S. airlines forecast record summer travel with airlines expected to transport 271 million passengers, up 6.3% from last year. Industry group Airlines for America said U.S carriers plan to fly more than 26,000 daily flights this summer, up nearly 1,400 or 5.6% over 2023, when they carried 255 million passengers. The summer travel season forecast is for June 1 to Aug. 31. Some airlines voluntarily trimmed New York flights last summer to address congestion issues and have raised new concerns about the lack of controllers.
