LHR>MAN this evening from A20. A slightly different experience from my ALC report earlier in the day(nothing known about G0) - We arrived and pre boarding already nearly finished. We asked gate agent had they called G0 and barrier opened and we were ushered thru the egates. A litter later they announce G0-1 to come forward and queue in tensiles. Escalator then turned on and we went straight down. Dispatch Manager was very proactive and actually said to us Are We the 2 Group 0s and first on the plane. What a refreshing experience!
