Wee update. Thanks to foldupJim for taking the time to reply.
Successfully travelled with my Mezzo in checked/hold luggage. In a soft case no less!
Bubble wrap over the pokey and delicate bits, deflating the tires, undoing the handlebar stem to fold smaller etc worked a treat.
My long forgotten baby arrived without a ding!
I did ask the airline to slap a fragile sticker on the case but the case was beat up by the time I got it home!
Thanks especiafoldupJim
