Flew MAN-LHR-TXL on Sunday 23rd and back on Friday 28th in CE/Business UK.

At MAN outbound, the flight was from Gate 9, where there was plenty of space to manage the queues and the new system seemed to be employed and working things might have been different at one of the 14x gates. The flight seemed to be fairly full, but I had an what seemed to be one of very few empty middle seats beside me - a possible effect of being silver with checked bag, or just a coincidence.

At LHR the new system was in full operation, CE before anyone else and others (I think including Golds), turned away to rejoin the queue at the back.

At TXL, I was one of the last through security, so missed the early stages of boarding, but I didn't notice any signs about boarding order.

At LHR for the flight to MAN, the sign was there, Business UK went first, and I did see some people turned back.

Despite all this, you still got people blicking the aisle whilst they arranged their belongings. Perhaps a couple of inches more seat pitch would have given them room to turn round in their seat space and leave the aisle clear.
