MAD Iberia Business Class Lounge T4S

Aeropuerto de Madrid-Barajas
Terminal 4

With a 3:15P departure, our driver picked us up at the hotel around 12:30P.
A short 20 minutes later, we pulled up to the new and cavernous T4. Not many pax at the LAN counters.

But 22 minutes to our concourse?? Don't know about the layout of this place, but we walked for 5 minutes, cleared security, then took numerous escalators just to get to the train. Then hopped the train to the Terminal T4S, 5 minutes and at least 3 miles away from the main terminal. Then more walking, passport control, more escalators, more walking and we were finally in the RSU concourse.

Yep, about 22 minutes later we arrived at the very pleasant Iberia Lounge. Spacious with numerous comfortable seating areas, with full bar and food offerings at each end of the lounge.

Not sure when they use this, but The Bistro was closed today.
