You guys don’t do maths? The recent low seniority upgrades are an anomaly owing to the lost decade of no hiring. A 7 year upgrade should be considered more like a 17 year number. Eventually the required seniority will climb back to the long term average.
The short haul fleet is going through a temporary increase before a long term decrease in aircraft. The long haul fleet replacement orders compared to the aging fleet size would not give me hope for rapid promotion.
