Hi all.
So I have just returned from my Lima trip.
Here are the results of my Group 0 experience.
1.AGP-MAD (Air Nostrum)
Signs only had Group 1-4. Gate agent asked me to wait around the area.
He did call Group 0 first. However, it was actually a pointless exercise as I knew it would be, because I was simply the first onto the bus.

By the time we reached the aircraft, I was almost the last one to board.
I don't have any issues with this really as how else could they do it.
2. MAD-LIM
Signs had Groups 0 and 1 together.
When boarding started both groups were called. So, in the case of Madrid for long haul? What's the point?
3. LIM-MAD
Now this one pleasantly surprised me.
Although the boarding zone was a combination of Groups 0 and 1, they actually called Group 0 first and I was able to proceed directly to the aircraft.
Very impressed with how the gate agents managed the whole thing. The flight was full, so imagine 300 people around the gate area.
4. MAD-AGP (Air Nostrum)
Groups 0 and 1 boarded together.
So, to sum up.............. In Madrid, the "hub" of Iberia they don't seem to be too interested in enforcing the new policy.
At outstations they seem to be on the ball.
