Travel expenses to Europe to look at properties

[Bob Malecki]

I'm a full time RE investor and my wife is self employed as well. We are planning a month long trip to Europe next year and part of the trip will be to meet with property managers or RE agents to look at potential acquisition to hold as a rental for short term rentals like AirBnB. I figure we can write off our accommodations and meals for the days we actually do the local meetings/viewing. 

Can we also deduct our expenses for flying over from U.S. to Europe?
