Off on a stag do next month. For reasons that shouldn't need explaining here, part of my outfit involves an S10 respirator (sans filters). The weekend is in Budapest and we're flying EasyJet from Manchester. Will I have issues with the respirator in hand luggage? I'm not planning on taking a checked bag. Direct.gov doesn't cover gas masks in the list of restricted or dangerous items, and while I'd expect some additional interest from the UKBA bods I'm hoping there would be nothing legally/formally holding me back. I'm working on the assumption that by not being a cock, treating the security bloke with a bit of respect and blatantly appearing like a harmless stag party they'll see the light and let me through. Coming back the other way could be another story. Any advice for that side of it?
