In terms of percentage of travel time, a 1-2 hour delay for a 20 hour trip between NYP and CHI would be the equivalent of a 6-12 minute delay on a 2 hour flight between the two. If a passenger traveling between O'Hare and LaGuardia/JFK would accept a 1 hour delay then the equivalent on Amtrak would be a 10 hour delay (a half hour delay on UA/AA would be a five hour delay on the LSL). If you're traveling LD, you should reasonably accept the possibilities of longer delays (ignoring the reasons for delays). I'm guessing Greyhound won't be much better if God forbid you took a bus between New York and Chicago, there will inevitably be traffic jams (one big reason I prefer trains to buses).
