I could have sworn I posted this already, but it's nowhere to be found. Weird.

I'm travelling LGW-IAH-MSY and I hope to transport 6 bottles of wine. I know that I'll have to pay import taxes on everything past 1 (or is it 2?) liters. I've heard that most airlines have some sort of box designed specifically for checking and transporting bottles of wine. Can anyone corroborate this, and are they available at LGW? What's the protocol on this? Thanks in advance.
