Well I run a global aviation safety consultancy. I pay public fares and don't get industry discount, so no frying me for it being easy. I use aircraft to get around between jobs, not working checking the aircraft whilst flying (I cannot do this within the flight crew limitation hours! I fly too much, not enought rest hours and too high a radiation dose for aircrew regulations.)

Teleconferencing does not work, on site inspections and looking into the depth of someone's eyes is the requirement. Also the wreckage doesn't fax well.

Some continents have lots of travel associated with doing business. For example, if you work in some European Commission sponsored projects, you have to travel to a couple of countries a month for meetings. Add a few Brussels coordination trips in and you are at one return a week to start with.

Add in normal business project based work with European overseas clients and that is at least one more return a week.

Now Australia for my main office with a SYD base has lots of hopping around the Canberra, MEL, SYD, BNE areas with hops to NZ as well.

Then you have to get from the London office to the SYD office.

Add in lectures and conferences for another long haul return every couple of months.

Add in one day inspections for insurance companies anywhere in the world and that is another set of bi-weekly long hauls (best done off London for ease of travel, SYD is not well connected for quick trips in that sense).

Add in the extra flights required for security reasons. For example, some sites may not have secure accommodation for overnighting so you have to fly back to the capital at night and then come back in the morning, with less than 6 hours in bed.

I am very lucky in that I get to travel all over the world. There are some unpleasant aspects in some countries. There are some countries that I don't like. There are some where I get very bored as I don't speak the language and it can be too frightening to go outside the hotel at night.

However, I love my job. What can be better than the view out of the window of a 747 on a clear day, computer switched on with in-seat power and a British Airways afternoon cream tea being served?

As for jet-lag management, well I have got a fair amount of experience in that department. I know what works for me but I have to admit to getting tired and certainly sitting in a dark radar control room after a long haul and 10 hour time shift at 3 pm local will start to see the head nodding slightly.

Just think off all of those miles available to spend going on holiday....

I have only used miles for a private trip once in the last 10 years. That was to fly to Barra, the only commerical beach airport in the world, where the timetable is tidal!

So that is why I travel so much, just a global traveller to get to work.
