I am not quite sure why this rating matters that much. Let's face it, if BA can make it no. 1. You think this really is completely reliable?
That said, Cathay may hv a lot of works to do. I am sure they must hv checked all the boxes that rocketed them up in the top league. There are certainly bad eggs in a basket, but, Couple of bad flights wont throw their recognitions down the drain, or just yet. I hv a strong belief that consensus prevails, the odd bad publicity isn't consider as consensus.
Also, bear in mind business transports also weigh on the convenience cx could offer, to an extent leisure transports too. Cx connections at major hubs like lhr, JFK, net et al are unrivalled, let's bear in mind all the factors in the bigger picture
Apologies to all for going off the rail a little.
