Well, Bangkok is the 3rd largest unserved long haul route in the world, and all those pax are routing through somewhere, so, unsurprising that EK is seeing a lions share of this.
I’ve been told it’s a 4 weekly A359 on the cards, which to me seems the perfect aircraft for the route to get it going. That is unless TG goes bananas and send in a HD B77W and really fare dump the route, but that won’t be sustainable.
