My dad once had a flight west that took off just before sunset. Apparently took well over an hour for the sun to fully set. Not quite perpetual, but the stretching of dusk was apparently pretty weird.
Yes a commercial airliner can go about 80-90% of the speed needed to match the earth’s rotation, so if it chases the sun, you will only lose a couple hours in a day when you arrive to a new destination 12 hours later.
