Hi.

I believe EK doesn't permit DXB-BKK on 418 because it lowers the yields; they would much rather have people fly on to SYD/AKL than sell 418 seats to those deplaning at BKK. This is why most tickets originating from SIN don't use EK433/404 etc (which start or finish in Australia) and rather random ones like EK352/349. You can waitlist but again that is problematic. The airline is a bit tardy in requests even tho it knows it has the seats. Really it's one big grrrrrrr
