Sure, there are night flights. That doesn't make the flight any shorter, though. It just gets you there earlier in the day at your destination. And, admittedly, Metropolis could be closer than New York. But on the east coast it will be about the same time. I've done a lot of flying from California to Washington D.C. and points in between, and the longest pole in the tent is getting from ground to plane to taxiing on the runway to lift off and back again, not the flying time. There's a saying among the Road Warriors "If you have time to spare, go by air." My personal horror is changing planes in ORD (Chicago). It is never a good experience. But we can assume that things work out the best for Lois. There would be less airport traffic and hence runway delays on a night flight.
