Dress box or Suit Carrier?

I'm using a canvas suitcase type box my dress company provide. They said they will wrap it with tissue so it doesn't get damaged and it fits in hand luggage

I asked my dress shop about this & they recommended putting it in a "trolley dolly" suitcase as this has hard shell so more protected & can take on as handluggage. i had been planning to buy a dress box

I had a dress box off eBay it came with acetone free paper I wrapped the day before I flew and put my dress bag on top, when we got too Vegas 10 hour flight i moved my dress into the bag and let it hang...It was fine it came home in the box too all fine, I took it as hand luggage onto the plane x

Have a look at the empty box company they do travel boxes.you can get 10% off if you use discount code FB15
I am toying between a box or a case. I wouldn't relay on the airline hanging your dress up once on the plane as they have very limited space, especially if it's a popular wedding destination and there are several brides on the plane all wanting the same thing. X
