And if that wasn’t enough, thunderstorms elsewhere in the East were already having an impact on air travel here and elsewhere Wednesday night. Early in the evening, Philadelphia International Airport was reporting delays of up to an hour for incoming flights, and 30- to 45-minute delays for departures. It got worse, with delays jumping to 90 minutes a few hours later — both ways. Boston, New York, Newark, and Washington were reporting even longer delays, three hours or more.
