Excellent find as my wife and I will be buying separate tickets within Spain/Portugal this summer. We have our return flights from Madrid to New York booked on AA #95 (yuk 757), but were trying to weigh our risks of taking an IB flight from either Lisbon or Seville to Madrid and connect to that flight same day. Heavy risk because the flight connections from Schengen zone to non Schengen zone in MAD can be difficult at times.
