I had a pretty opposite experience, where they announced zone 1 boarding, did not announce zone 2 and skipped straight to 3. But as I knew J was only 2 rows of 4, no way those 20-ish people all were in zone 1, I doubt there would have been many, if any, Ultis. So I just joined the zoo instead.

But yes, the zoo of Zone 4 and Zone 5 people blocking the access when they start with 1/2 is annoying. In Barcelona, they at least have dedicated lines for 1/2, 3, 4 and 5, enforced with (admittedly) too short tensa barriers. But it's something.
