Wasn't sure which were the apples and oranges to even begin comparing it seems. I was thinking of train trips locally like commuter trains for about 30 - 40 miles v. short flights a state away because for a train trip to be made a route needs to exist, and those tend to be commuter trains. I wouldn't suggest a train to be an aggregately shorter time period for a long distance trip.

Another factor to consider is that total time for air travel for the covid context should include sitting on a tarmac and loading / unloading.
