LHR HEL LHR return on wide body. No difference to any other time in terms of carry on at either airport. Didn’t notice any checks either but was in Group 1. I didn’t go to checkin desks at all as didn’t need to.

When going through checkin area at HEL I did see some cabin sized bags being checked in but no idea if because enforced. Just something I noticed.

Priority security however was super slow - slower than normal lines. Only one scanner in use and also bag scanning seemed particularly slow with a lot being pushed to the side.
