Hi thishonestfood,
Thanks for getting in touch with us.
I’m afraid variable pricing is not supported like that at the moment.
If you think that is something you would like as a feature I encourage you to visit our User Voice Page and either upvote an existing request or make a new request there. Please provide as much details as you can. A scenario description would be very helpful too.
What you can do at the moment is setting up different tickets with different prices.
Another approach, which might work for you is using the WooCommerce product page to sell tickets. Here is an article on how you can achieve that.
Hope this helps.
Cheers,
Andras
