Now we have 120 airlines across Europe with negotiated fares. Of course we deal with 600 airlines as everyone else does. The same goes for hotels. We have 14,000 hotels worldwide, not just in the States. So the barrier to entry there and with cars also is quite big as well.
Technology is a barrier to entry.
When you have negotiated fares and published fares you need a different kind of booking engine. Expedia has done a good job here. They have got a booking engine that can do both like we have. So those are the two big barriers. The third is that you do need travel management.
