I will be landing in Barajas T4 on American and changing to an Iberia flight to Valencia. I can't remember if I will have to go through security again in Spain or if I will remain in a secure area for the entire process of changing planes.
I'm asking because I know that I can carry my hiking poles onto the plane in the US, having done it many times, so long as they are broken car rental companies in las vegas down and have rubber tips on the end. But I don't know about the policies in Spain and would hate to have them confiscated when I'm rushing to get onto a domestic flight and don't have enough time to go out to ticketing and check them.
As noted, you'll have to go from the arrivals section upstairs to the departure area, passing through both passport control and security. Their may be some problems with the hiking poles, but you never know how security is until you get there. Things change often. I went through security in Madrid carrying a new (and expensive) umbrella, which was later confiscated by one of the idiots at Heathrow when we had to change planes and pass through security.
Thanks -- I was afraid of that. I will only have my backpack and do not want to check anything. The last time I checked my hiking car rental companies in las vegas poles, they were lost somewhere between Chicago and Madrid. I had a few hours before my train and was able to buy a replacement set but it was a real hassle. I usually take a train from Madrid to where I start to walk, but this year I decided to just continue on to Valencia from Barajas. I suppose that if they try to confiscate the poles, I can just forfeit my ticket and get a train, that would probably be cheaper and less of a hassle than replacing them in Spain. (Just checked the AVE prices and it looks like 72 euros to Valencia, but with my 40% golden age discount, that would be about 40 euros, so that will have to be my fallback plan).
I don't think the problem will be with Iberia, since the poles will be in a disposable duffel bag, my fear is the unpredictability car rental companies in las vegas of the security at the airport. Robert's experience is exactly car rental companies in las vegas what I'm afraid of. I know the airport in Santiago de Compostela won't let poles through security, but many people have had inconsistent experiences across the country.
