At the risk of sounding too ambiguous, we are open to any unique or creative possibility.
Although we spell 'Hubb' with two b's, the word hub quite literally means the central part of a wheel. In the context of air travel, it basically refers to a major center (ie., major airport), or a central meeting point.
If you would like to draw on that allusion for the logo you can -- or you can feel free to be slightly more abstract.
The word 'Hubb' itself can be spelled in all capitals or all lower case or a combination of whatever you believe looks good.
In general, we would love to convey our sense of youthful passion through our logo.
A JPG or GIF file would be nice. Perhaps one version that is a bit smaller in size (and therefore less resolution) but is more than adequate for being utilized on a website, and another version which is much higher resolution to give excellent quality when printing.
Thanks for taking the time to check this out!
