We're business travelers too, and share the pain of being misinformed, or worse, mislead by airlines and luggage manufacturers about what will and will not fit in the overhead bins. During one particularly trying search for overhead bin space, inspiration struck, and this site was born. Now you can figure out ahead of time what the situation is likely to be and avoid it altogether or at least brace yourself accordingly.
Wow, cool!
Indeed. Go ahead and get right to it - you can either search for a bag/bin report or write about your own experience.
