Looking through the dashboard at lounge options, I note that from Kiev KBP it states entry is "By invitation, obtain one at check in", but also "Standard BA rules". Traveling with hand baggage only does this mean I still have to present myself at the desks, or will my mobile boarding pass suffice?

Apologies but I've not seen this before and couldn't see the answer within the dashboard. If I do need to visit the desk, how far in advance if the flight do they open at KBP in experience?

Thank you all.
