This is the theory of the echo. Sound is reverberated ONLY AFTER it has reached something (such as a mountain, building, house) in which it can be bounced off, back into the atmosphere, and then back to your eardrum. The seconds it takes to reach a place is the time it takes an object to find that of which to bounce off of.
Simple! Great...great...great question!

Sound takes longer than a few seconds to reach a far place. Sound takes about 5 seconds to go a mile. Sound would take more than 4 hours to go from coast to coast of the USA.

Sound doesn't really travel that fast. Figure about 700 miles per hour. So, if you need to go 1500 miles, it's still more hten 2 hours.
Jet's dont really travel at the speed of sound, closer to .8 or .9 mach, and they're much slower climbing. In the first and last part of the flight, FAA rules restrict them to 250 miles per hour.

Because the speed of sound isn't all that fast. its about 770 miles per hour. So a flight from NY to LA still takes a little more thanr 4 hours at the speed of sound

Passenger jets don't. These are military jets. I don't think most airline travelers could stand the G's exerted in breaking the sound barrier.
