Hi Aparna,
Thanks for reaching out! We’re still in the process of developing full support for recurring event tickets, so the functionality that currently exists in Events Calendar PRO and Event Tickets Plus is not yet complete. However, this combination may work for your stated needs: a ticket created for a recurring event will be applied to all events in the series. Registering for one event will also allow a user to attend any event in the series. It’s worth noting, though, that users will only be able to check in for one event in the series–after a user has checked in with a purchased ticket, they will not be able to use that ticket to check in again. This behavior may also change somewhat as full support for recurring event ticketing is rolled out in the coming months.
I hope that helps–please don’t hesitate to let us know if you should have any other questions here! Cheers, and thanks again!
