For F CX-QF-BA-LA-AA (F not offered on IB, EI or AY; but AA is competitive with BA on some routes, LAX-LHR and ORD-LHR for example and superior for DFW-FRA).

For J night flights QF-BA-CX-IB-LA-AA-AY-EI

For J day flights, CX-QF-IB-LA-BA-AA-AY-EI (but on some routes AA would place higher).

QF and IB have good bed comfort in J, while CX has better IFE and FA service. AA is erratic but some routes are dependably good and AA offers a quality product. LA has great wines, which cover a multitude of sins.
