Bite the bullet and get the B&R Deluxe Wheeled Garment Bag. I have one and it is the only garment bag I've used where my suits come out with few wrinkles if any. It's not cheap and must be checked but it is a very good piece of luggage and I don't care to spend the first night of a business trip hunched over an ironing board because I cheaped out on my luggage.
