As you all know, I am a lawyer, but now also the owner of an espresso/coffee shop. Both occupations require business cards, but they are necessarily going to be different. For example, the coffee shop ones will have something on the front and back. In this small business owner class I'm in, the first thing they pounded into our heads was to use both sides of the card, otherwise you're only doing half the job of selling yourself and your business. My lawyer card is only one-sided because it's all I need to let people know who I am and what I do.
Since your cards will be used to sell yourself in the same way my coffee shop cards is selling my coffee shop, it would be wise to combine the two suggestions above from F172 and Spoilers.
A logo of an airplane or something would be nice too. It will give people the idea, immediately, of what you are doing. If you have a website, include that as well (but I wouldn't post your Facebook or Myspace kind of stuff).
Check out the business cards templates available online. You might find something suitable. If not, go with a designer who will make several versions and let you choose. PM me if you'd like the ones I've talked with recently about my coffee punch cards.
For fun, take at look at this website. Very creative, eh?
