My camera.
What type of suitcase do you carry?
I have a bit of a bag fetish - I own around 15 bags so it's nearly always a different one.
What's always in your hand luggage?
Everything under the sun - often a pocketknife which gets confiscated at airport security.
Are you a planner or last-minute packer?
I'm a last-minute packer. Everything is thrown in literally two minutes before I race out the door, usually late.
What's the best thing you've brought back from a trip?
An ornate pottery Humpty Dumpty. It's a cross between a horror doll and a royal Copenhagen. He's balancing on my mantle awaiting a great fall.
Favourite or most exciting airport to land in?
Pisa, in anticipation of the pizza.
Best packing tip?
Reasonably obvious: put your knives in your check-in luggage.
Most memorable trip?
The unexpectedness of Poland.
What do you do while on the plane?
Personal admin and drink as much free booze as they let me.
