Business travel is a specific term determined by the IRS to describe travel away from your tax home that is "substantially longer than an ordinary day's work" and that requires you to sleep or rest while away from home.
You must also sleep away from home to be able to deduct these costs. The travel must also be "temporary" (lasting less than a year).
