What's odd? Having to let them know I'm going? It's all got to be done properly.
I didn't give them my new address though. I don't really want them to know where I'm going and I already regret even mentioning it would be somewhere in England.
When I booked my flight at the travel agent's, they only asked for my name there. Then the agent looked at the screen and read out my address that she somehow managed to find through their database. I've never booked with them before so I wonder why it is legal to be able to get people's addresses just like that.
