I found a store in Madrid, would have to check a map, they had 120 film and even sold LF cameras second hand but had no idea where to get LF film Prices are higher than the UK and far higher than the US so take what you think you'll need with you.

Carry on scanners in Europe are far safer than those in the US, no hand inspections needed and they aren't given.

I flew through Barcelona & Madrid last month with 30 rolls of film, they were scanned at Izmir, Istanbul, Madrid, Istanbul and had already been scanned UK - Birmingham and Istabul before. Never any problems I do this very regularly.
