So there's this snowstorm coming to NY tomorrow. Airlines are already starting to cancel flights into NY. I have a friend flying into EWR from SAT on CO. CO already cancelled that non-stop. I put her on an early connecting flight through IAH.

She could get stuck there, but here's my theory:

CO would prioritize what few slots were available through the weather into EWR for 1)international flights, and 2)flights from their domestic hubs.

Is this a reasonable theory?
