What's your preferred mode of travel - surface or air?

What do you like/dislike about it?

I've done a fair bit of air travel mostly for work during 2008/9/10. All domestic travel bar two overseas trips by myself in the mid-1990's.

I don't like air travel though and much prefer to stay on the ground. I'm not a fan of water travel though I've hardly done any.

I've never worked in aviation or marine industries.
