guys,
Little advice required.
I'm travelling on a BA cityflyer flight tomorrow out of LCY and I would like to take with me a piece of art for my abode abroad. The art has been wrapped and protected for the flight by the auction house and the box is now 1 metre by 1 metre square and 10 centimetres deep. Do you think I would have any problems checking this in as hold luggage?

I know it breaks BA's baggage size limits but thought I'd check

Thanks
