It was interesting to see that the umpires appointed for the Trans-Tasman series were the two West Indian former soccer referees. But now it seems Bucknor is to be replaced by Koertzen.
The reason is "travel difficulties". With the ICC, the real reason could be anything, but I can certainly imagine travel difficulties if the umpires are still forced to rely on Emirates. I'm not criticising the airline (my experience with them is mostly good), but they, or any other airline, are not exactly in a position to offer the best routes between the different cricket nations.
