I flew from Gran Canary to Lisbon Portugal on TAP - Air Portugal. Easy 2-hour flight, but the Lisbon Airport was a crazy experience!  I had 2 hours, between the connecting flights, but spent the time being routed all through the airport. First try, they routed me in a giant circle and I ended up going through the long lines, to clear customs, twice!  Second time through I followed different signage, but again could not find my flight listed anywhere on the monitors where I was. I finally figured I must have to change terminals for the connection. When I went all the way through baggage claim in first terminal I came out of the building and saw another terminal across the way and then finally found monitors showing my flight.  Shockingly it listed my gate and flight as FINAL CALL. I now had to boogie through this new terminal's security (TSA) and the extremely crowded duty-free shops and tons of strolling passengers. Then, I hear my name being called over the PA system and I am sprinting to the gate, arms waving and thank goodness they saw me. They radioed the taxiway bus, and he quickly got me to the plane. I boarded to lots of stares and breathed a sigh of relief! They shut the doors right behind me and we were off!
