Hi Thealy59,
I need to make sure we are talking about the same thing.
If you just decided to sell a ticket that you would not use three years later, this money would be reported on the schedule D, form 8949. This would show long term gain, and sidestep any self employment tax. If you receipt where you bought the ticket three years ago, that would be the "Basis" and the sale price would be the proceeds. As you might suspect, documentation is going to be key for this transaction.
If you deal in reselling tickets and showed this ticket as inventory on your small business, then yes, you could deduct the cost three years later. Most people don't fall into this area though.
Here is another article that speaks to your issue:

Thanks for reaching out and I wish your team luck this year,
Louise
