ABZ-LHR this morning: new boarding policy done as described and enforced. People waited behind the tensa barrier, it all went smoothly.
New carry-on rules: unsure about the enforcement. Some people with 2 bags had yellow tags, some did not. It did not seem to have been followed, and it was certainly not announced.
No problem though as the A321 was around 60% full, so enough space for all.
