I'm oneworld emerald and two of us are travelling FCO-xMAD-TLS in September. Inbound on a 320 and outbound on a CR2 (YW). We are travelling on a LONE4.
We have a 2½ early afternoon transit at MAD.
Never having flown IB before, which of the two terminals (T4/T4S) should we arrive/depart and what would be the better of the three IB lounges to use?
Is/are there any tips/advice than any may have for us.
