Major U.S. airlines have issued travel waivers for passengers flying to or from East Coast airports spanning from Portland, Maine, to Washington, D.C., in response to forecasted heavy rain and thunderstorms. These waivers allow travelers to change their plans without additional fees. The Federal Aviation Administration (FAA) has implemented ground stops at six East Coast airports due to severe thunderstorms, causing widespread flight delays and disruptions. The affected airports include major hubs in the metropolitan areas of New York and Washington. The weather-related interruptions have led to significant travel chaos across the Northeast and Mid-Atlantic regions.
