FAA Advisories Point To Weather-Driven Departure Delays

What Should Disrupted Travelers Do?

• Check airline notifications before leaving home.
• Monitor gate changes through airport information screens.
• Allow additional travel time for security and check-in.
• Rebook quickly if flights from JFK, Atlanta, or Boston change.
• Keep essential medications and chargers inside carry-on bags.
• Confirm baggage status before leaving affected airports.
• Stay updated through your airline’s mobile application.

Why Are Disruptions Continuing Across The United States?

Severe weather continues driving disruptions across large parts of America. Slow-moving thunderstorms are expected to soak the central and eastern United States through the week. Forecasts warn that repeated rounds of heavy rain could trigger flash flooding. The greatest concern stretches across portions of the Plains and Midwest, including Chicago, where thunderstorms may repeatedly pass over the same areas. This weather pattern increases the likelihood of departure delays, ground stops, and operational slowdowns at major airports.

Weather also affected airline operations along the East Coast. JetBlue issued a travel waiver covering Boston, JFK, LaGuardia, Newark, Philadelphia, Washington Reagan, Westchester County, and Long Island/Islip because of expected severe weather. Eligible travelers can change flights without paying change fees, while customers whose flights are cancelled may request refunds.
