I've seen some enormous items of hand luggage when I've travelled on BA, some have amazed me!

With our wedding coming up in April, the future Mrs MDJ would really like to take her dress in the cabin and not put it in the hold and I have found a nice box which is a little larger that the permitted but has pretty much the same volume.

It's 50 x 75 x 15 cm (deep)

We're booked in CW on the Upper Deck and I've seen the crew store quite large items to the right of the stairs.

Suggestions please?
