Please note - The Extras section on your account page can take up to 48hrs to appear after purchasing tickets so the best place to add them on is at checkout. If options do not appear at checkout or through your account then these are sold out.
It's great to hear that you want to enhance your experience with us! Please carefully follow the steps below to get that sorted:
On a Smartphone:
Once logged in, look for the three lines in the top left side of the screen. Click on those and select 'Extras' from the drop down menu shown.
On a PC or Tablet:
Once logged in, look on the right hand side of the page for the 'Extras' heading.
