Hello Jamie,
Thanks for using our plugins and welcome to the forums! That’s a great question there.
We are slowly working towards achieving WPML compatibility for all our plugins. Event Tickets and Event Tickets Plus is of course also on the roadmap for that.
We are currently planning to make these 2 compatible with WPML in version 4.5. If all goes according to plan, that should come in 3-5 months.
I hope this answers your question and it will be still in time for your project.
Let me know if you have any other questions.
Cheers,
Andras
