Anyone’s weekend will be planned well in advance. The disposable income to decide on a Monday to have a bimble to Glasgow or Edinburgh at the weekend just isn’t there for LDY’s catchment. Ergo, people WILL book leave for weekends away etc. And if the 11.30 return flight doesn’t suit (all change come April as 757 says above) then they can fly with EZY to BFS and hope they’re as lucky as you are with on-time flights to that airport, with that airline.
