90 day Schengen rule.
I am a bit confused over the 90 day rule.Am coming out from UK 13th June to 13th July,then I want to visit again end September,beginning of October for 3 weeks.I wont then be visiting until next Spring.After returning home to UK 13th July,do I have to wait 90 days before I can fly out to Spain again,or would this only apply if I had stayed in Spain for 90 days June/July?
I previously thought I would have to wait 90 days before returning to Spain,but now I am not too sure.Any advice very welcome.
