You must be a bad packer or wear cheap ties. I have little suitcasemanship, and I find it takes a lot to wrinkle a good tie. Are you wearing low-end silks? We don’t want to iron our ties, fellows; that’s a job for professionals. However, should you arrive in Bismarck or Peoria with a wrinkled cravat, hang it in the hotel bathroom and run the hot water so the bathroom fills with steam. After ten minutes or so, the wrinkles should vanish. If you’re concerned about your carbon footprint, try rolling the tie up next time and sticking it in your extra pair of shoes.
