It's a huge opportunity waiting to happen. If you add Easyjet and the other discount airlines, and then add trains in for close cities, it would be a huge hit.

For example, I live in Nice and wanted to go to Malta. The ticket was 200 Euros. But I found I could take a train for two hours and go from Marseille via RyanAir for 20 euros.

The same is true for Last Minute deals. Czechs will spend twice as much for, say, a week in Egypt as a German in a city two hours away by train (Prague - Dresden).
