Airlines warn changing daylight saving time would disrupt scheduling

Airlines are warning that the proposed Sunshine Protection Act, which would make Daylight Saving Time permanent, could cause significant scheduling and connectivity disruptions. The industry argues that any transition requires a carefully planned implementation timeline to manage global network complexities.
Why it matters
The legislation could fundamentally change how the U.S. manages time, impacting everything from international travel logistics to daily business operations.
Airlines are warning that changes to existing practices around Daylight Saving Time (DST) would have a major impact on the industry and that changes would need to be implemented over time to account for challenges it would create for scheduling. Airlines for America (A4A), a trade group that represents leading air carriers in the U.S., released a statement this week which warned that changes to DST "would have considerable implications for aviation, including passenger disruption, crew and aircraft positioning, and domestic and international connectivity issues." "Airlines operate expansive interconnected domestic and global networks that are reliant on stability and predictability. Any changes would need an implementation timeline that reflects these global complications," the group said.
