Sorry if this is in the wrong place or has been answered before but I can't find an answer.

I have a GUF2 and was wondering if there are any routes BA flies where the plane does not have a world traveller plus cabin? I'm not sure if there even is any, but I thought my upgrade voucher might then charge economy avios for a club world flight?

I'm probably wrong but I'm sure one of the experts in here can help.

Thanks in advance!
