Hi,
Flying AA Chicago to Glasgow, AA to Heathrow, then BA. I believe that a cardboard box is acceptable as checked luggage as long as it is under 62 inch total dimensions. Any reason I cannot wrap it in plastic? Trying to reinforce it as much as I can for a fragile item.
Can I, should I put fragile labels on it?
Any advice appreciated. Thanks

I am packing a shipping box inside another shipping box with padding and hoping for the best.
