My first experience of Group 0 this week was at DUB and it worked perfectly. Flight was delayed so I expected boarding to be a scrum but Group 0 was called and enforced (a few funny looks from a couple of Group 1 pax as I went over as I was the only Group 0 who came forward) and I was first onto the tarmac and onto the plane - which meant I got that hallowed single overhead bin above 1A/D.
Due to the delay I ended up with 50 minutes between landing from DUB and departing on my JFK from C gates. This would have been a perfect time for a little GGL assistance but I guess they were busy walking people from TFW to the CCR.
Got to the gate as they were lining up Group 4 so didn’t see if Group 0 was called, but by the way the 1-3 queue was being actively guarded did wager they were doing it properly.
