The airfare, though, is usually 100% deductible even if you mix business with some pleasure.

Fuel prices---cost of jet fuel can have a HUGE impact on airfares.

On the general topic of education, I figure in an average year I spend $20,000 - 30,000, including training, airfare, hotels and such.

POOR CHOICE- Airfare & hotel charges for 1 person, assuming trip.

Travel expenses can be very tricky - there are a bunch of bifurcations based on if the trip is primarily for personal, primarily for business, or somewhere in-between - including the allocation of airfare and other costs. 

Does the pricing include airfare?

You can deduct the hotel, airfare, Uber or vehicle mileage as travel expenses. 

With several large cities within driving distance 6+ hours - the demand for recreational activities I believe is a safe play without the requirement for airfare. 

Can I write off all expenses from the trip, such as hotel, meals and travel costs like gas, or airfare?

The teachings free, you have to pay for airfare and hotel, I'm assuming.
