The OTP of the ORD/JFK routes have been atrocious from MAN this summer.
Sadly, it appears that on some days the pax on the BHX B757 a/c could be accommodated on the MAN B767. If seat maps overall are anything like accurate on the morning of departure, loads sometimes appear to be only 50-60% on both flights which for this time of year seems very disappointing. A clearer picture will emerge from the CAA stats. for BHX, but MAN's for JFK will be a composite figure including DL and TCX. Goodness knows what yields are like for AA. Ironically, ORD which was dropped for 3 months in the winter, seems to be performing much better than JFK.
Fortunately for MAN, UA often look to be 80% and higher (on IAD as well) and DL usually at least 75%.
