Some international, some more than others depending on what airframe. Even the phenoms go to Mexico, Canada, the Caribbean etc. The crew should work together to clean the plane. The smaller the plane the easier it is to clean! You don't usually get a long layover unless they are flipping your duty from mornings to evenings to have you fly a late trip. Then you often get flipped back later during your tour especially if you are out for 8 days. Good luck! The last class I spoke with said they were about 50/50 between phenom and challenger
