I proposed an idea to speak at re:publica in Berlin, so I travelled domestically to speak. The event gave me a free ticket, and I was not paid to speak. The event did not pay for my travel and accommodation. My employer did not pay my travel expenses, and I took unpaid time off to speak. It took me 4 days to prepare for my 45 minutes speaking slot, and I had a mostly good time. I'm a woman who has been speaking for 5 years. This was a for profit event.
