It seems like some airports and airspace are still no-fly regardless of a/c mode.
Don't forget bus services if you are traveling on the continent. Also, one could use a combination of public transport and commuter rail or regional train to get somewhere if hi-speed trains are overloaded. Anticipate long travel times and crowding if you choose that itinerary.
