LAX_LHR ... Re-read the line in my post which covers DELTA AIRLINES and the MAN-ATL route. It does not differ in content from what you say so nothing to be confused about here?
North West ... I agree completely that 'seats' are a preferable data source for forecasting than 'movements'. However, I don't have all the aircraft configs available or the time to produce such an in-depth analysis if I had, particularly on LHR with the ever-changing mix of A319/A320/A321 equipment. Hence the method I used which appears to have made the point sufficiently. Also, thankyou for the correction re Jet2. I had hypothesised that the B738 + B752 combo replacing the proposed A333 routes and the absorption of the former Blackpool programme would have put us in positive territory. Disappointing if that is not the case.
