To say the Travel Industry is dying a slow death is total garbage. They have to slim down and become more efficient like any other industry. Can you imagine a busy executive who needs to do a 7 sector itinerary and book 5 hotels and car hire making his reservation over the internet. Not only will he (or his secretary) spend hours of valuable time, hows he going to pay?. Use a credit card for payment to multiple suppliers. His accounts department would go nuts.
What happens when he wants a refund ? What happens when he wants to change the reservation? The internet may suit certain travellers but certainly not everyone. It will operate as a supplier alongside the travel industry but wont replace it whilst there is still a need for people to talk to each other.
