The transport sector is an area of the economy showing particularly good signs of strength. Long-haul air travel is beginning to recover from the 9/11 aftershock, even bus travel increased by 1% last year, reversing years of decline. Whilst massive investments are being made to improve transport infrastructure, the work itself adds to transport and travel costs through congestion, delays and disruption. Legislation is also forcing up costs in many areas, presenting challenges to operators that demand investment based on changes in thinking and approach. Responses to this take many forms, the rapid expansion of low cost, no frills airlines being a prime example.
