Traveler Action Checklist

1. Check your flight status via airline app or FlightAware before heading to the airport.
2. Contact your airline directly to rebook — activate disruption waivers proactively via app.
3. Know your rights — US DOT mandates full cash refunds on cancelled flights, not just vouchers.
4. Keep all receipts for meals, hotels, or alternative transport — may be reimbursable.
5. Consider alternative airports — Ronald Reagan Washington National (DCA), Washington Dulles (IAD), or Philadelphia (PHL).

Passengers like Jean Marie Davis, rerouted from DCA to BWI, highlighted the confusion: "I've never been to this airport, so I am just lost." With crosswinds at 30-40 mph and lightning risks, expect changes by the hour.

Storms across the East Coast, including Tornado Warnings in Maryland, triggered FAA ground stops from 2:45 p.m. to 4:30 p.m., with delays lingering into the night. BWI's role as a Southwest hub amplified the national ripple effect.
