A powerful band of thunderstorms swept across the US Northeast on 15 June 2026, pushing the country’s aviation network into one of its most severe single-day disruptions of the summer. By the end of that day, airlines had recorded 855 cancellations and 7,773 delays nationwide, with the Northeast bearing the heaviest impact.

Airports Worst Affected

LaGuardia Airport in New York logged the highest number of cancellations in the region, with 187 flights grounded and a further 268 delayed. John F. Kennedy International Airport saw 77 cancellations alongside 265 delays. Reagan National Airport in Washington DC recorded 131 cancellations, while Newark Liberty International suffered 327 delays. Other Northeast hubs, including Baltimore/Washington International, Buffalo Niagara, and Philadelphia International, also reported significant ground stops as the storm system moved through.

Nationwide, major carriers including Southwest Airlines, American Airlines, Delta Air Lines, and United Airlines were all heavily affected. Officials noted that the FAA issued ground stops at multiple hubs simultaneously, preventing flights from departing even at airports not directly under the storm. This FAA cascading effect — where ground stops at one hub back up departure queues across the entire network — is the main reason disruptions from a regional weather system affect flights in cities hundreds of miles from the storm.

Active Waivers Through 17 June

JetBlue issued formal travel waivers covering flights to and from Northeast cities including New York, Newark, Washington DC, Philadelphia, and Boston, allowing affected passengers to change or cancel bookings without fees for travel through Wednesday, 17 June 2026. Other carriers, including American Airlines and Delta, issued similar flexibility waivers for the impacted window.

As of the morning of 17 June, some residual disruption remains. Airport authorities and airlines advised passengers to check their flight status directly before heading to the terminal, as knock-on delays from the backlog continued to affect schedules overnight.

Your Rights When a US Flight Is Cancelled

Under US Department of Transportation regulations, passengers on US domestic flights and inbound international flights are entitled to a full cash refund if their flight is cancelled and they choose not to rebook. This applies regardless of whether the cancellation was weather-related — airlines cannot substitute a voucher for the refund unless you actively accept one.

For weather cancellations specifically, airlines are not required to provide hotel accommodation, meal vouchers, or compensation beyond the refund. The rules differ from EU Regulation 261/2004, which European passengers are sometimes more familiar with. If you were stranded overnight, your travel insurance policy is the primary mechanism for recovering hotel and meal costs — most policies with trip delay cover activate after a 6 or 12-hour delay, depending on the policy terms.

What Travellers Should Do Now

If you are flying to the USA or have a connecting flight through a Northeast hub today, we strongly advise checking your airline’s website or app for your specific flight status. If your flight was cancelled or significantly delayed during the 14–17 June period, you may be entitled to a refund — see our guide to US flight delay compensation for the rules that apply to international visitors.

Travellers with upcoming itineraries in or through New York City should allow extra time to and from the airports, as ground transport was also affected by the storm system.

Reducing Risk for the Rest of Summer

Summer convective storms are a recurring feature across the US Northeast and Midwest from now through mid-August. Afternoon thunderstorms develop quickly and can produce ground stop conditions within minutes. The most reliable mitigation strategies are to book morning departures — aircraft are already on the ground, not delayed from a previous sector — and to avoid tight connections through the high-risk hubs of LaGuardia, JFK, Newark, and Reagan National.
