"How long is the flight?"
Translation:Quanto tempo dura il volo?
This time i tried lungo... but "quanto a lungo" as advised by my reference book! My dictionary tells me that "quanto e" is for physical distance, as in "how long is the road", while "quanto a" is for duration. I'm giving up on this one,,, better buy myself a an extra heart in the store and pass it next time it comes up!
