My cat and I are moving to England and she has to be placed in the luggage compartment?

Can you answer Julia B’s question about Luggage?:

What can I do to make this easier on her? I hate the thought of her being in her carrier for the better part of the day even with good weather but how can she “go” and how can I set up her food and water? Help!
In order to comply with the laws in England my cat has to be in the luggage compartment in addtion to some other minor requirements. We want to make a good impression on the customs & immigration people :-)
