I’m not sure what you mean by ‘northern cities’ as London based politicians and commentators tend to lump together all ‘northern cities’ (north of Birmingham or the Potteries?) However, having lived in all of the following, I can assure you that Teesside, Wearside and Tyneside are very different to Manchester or Leeds.
JJ ‘The number of package holidays sold to ski resorts from northern cities would tend to suggest that it is not accurate…’
My post specifially referred to Teeside and as far I’m aware, even in normal times, there aren’t flights from Teesside/ Durham airport to any European ski resorts.
Undoubtedly some folk in North Yorkshire’s Barbourland (like Northallerton?) ski, but you’ll find their ilk anywhere…
