You're quite right regarding IPEX is a particularly prestigious show, and you would expect that passengers on routes from Germany and the Low Countires, plus DXB (connections from the sub continent) would be up as visitors and exhibitors to IPEX are concentrated from those areas.
You can be sure that yields on these routes, during this show, will be particularly good, though from personal experience, the ash cloud despressed visitor numbers at IPEX, and certainly some of those people that did attend decided to arrive by road rather than air to be sure they actually got there!
