When "business casual" attire won't do, but you have a long flight, a long trip, and will be checking your baggage, what kind of suitcase is best to keep a business suit looking nice? We usually travel more casual with smaller, softer bags, but not this time. I remember my dad's Samsonite or Invicta hard-sided "two suiters" from the 1960s but I don't know if they make them any more. I don't mind spending a reasonable amount, but am not a fan of truly high-end luggage for many reasons and will not be looking at Hartmann, Vuitton, etc. Are there any other strategies? Maybe SeatGuru shows whether the plane has a hanging coat closet, and if it does, the suit could travel on a hanger in a garment bag (or board the plane wearing the suit, with casual clothing and a soft garment bag in the carryon, and then change into casual in the bathroom and put the suit on a hanger?) Jut flying in the suit is not an option on a long flight or redeye -- I am afraid it will become rumpled, stained or smelly.
