I think my head cold is preventing me from interpreting the Madrid airport website...I'm trying to figure out the best luggage storage to stash my bag at the airport and catch the metro into town for an overnight stay. The metro appears to only stop at T2 and T4. I'll be flying in to Madrid on a domestic Iberia flight (T4, maybe?) but will be leaving on an international flight on Delta (T1, probably). I assume but can't confirm that the left luggage is outside of security, so no matter where I leave it I'll be able to retrieve it upon my return?
Has anyone done this and have practical advice? Thoughts appreciated (and I'm hoping this is an on-point, not pointless post so I don't offend the regulars!)
