I was invited to speak at Prairie Dev Con in Winnipeg, so I travelled internationally to speak. The event gave me a free ticket. My travel and accommodation was fully covered by the event. My employer did not pay my travel expenses, and I used my PTO to speak. It took me 4 days to prepare for my 75 minutes speaking slot, and I had a great time. I'm a man who has been speaking for 10 years. This was a not for profit event.
