The DOT refund rule
The DOT refund rule (14 CFR Part 260) covers every flight to, from, or within the US, including flights at BWI. If your flight is cancelled or significantly changed and you decline the new flight and any voucher or credit, the airline must refund the fare, taxes, and unused paid extras to your original payment method. That applies whatever the cause, including weather.
A significant change includes departing 3+ hours earlier or arriving 3+ hours later than scheduled on a domestic trip (6+ hours international), a different airport, extra connections, or a cabin downgrade. Refunds are due within 7 business days for credit cards and 20 calendar days for other payment types. Accepting the rebooked flight or a credit generally ends the refund right.
Meals, hotels, and rebooking
On the DOT Airline Customer Service Dashboard, large US airlines commit to free rebooking and a meal or meal voucher for 3+ hour waits when the disruption is within their control. All except Frontier also commit to a hotel and ride for overnight disruptions. Weather and air traffic control usually fall outside these commitments.
A local tip for BWI
Southwest flights often continue on to other cities, so a morning delay can follow the plane all day. Check the inbound flight's status in the app.

FAQ
Does Southwest give hotels for cancellations at BWI? On the DOT dashboard, Southwest commits to a hotel and ground transportation for overnight disruptions within its control. Weather usually isn't covered.
Can I request a refund if my BWI flight was cancelled for weather? Yes. The DOT refund rule covers cancellations for any reason, as long as you decline the rebooking and any voucher or credit.
What if I already accepted a travel credit? Accepting a credit generally ends the refund right under the DOT rule. You can still ask the airline, but it may treat the credit as your choice.
