I am coming to america for a 9 week holiday and thinking of booking a flight with Southwest on 29/ September this year from Charleston to Las Vegas. the stop over is in Nashville but only gives 35 minutes to change planes to complete the journey to Las Vegas. Do they just transfer luggage to the other plane? Also, this does not seem enough time to get off one plane and onto another. Have never been to America before and not sure how this works. Can anyone help?
