Beauty school only teaches you so much. It's important to keep to keep up your skills by taking courses, which can often lead to fun travel opportunities. Maybe it feels a little like cheating to be able to go to San Diego and learn the latest balayage techniques while also dipping your toes in the sand. So what's business versus personal and how can you deduct as much as possible?

First, let's talk about the things you can deduct assuming you are performing business activities every day of your trip.

Flights
As long as the primary purpose of your trip is for business, your flights are deductible. If you use points, then your cost is zero and there is no deduction. Pro tip: save your points for a fully personal vacation. 

Uber, Lyft or taxi
Any transportation you have to take during your trip is also deductible as long as it's for business. This could include traveling between the airport and your hotel or between your hotel and the work location.  

Baggage...
