Approx 40 HON’s pass through Warsaw on a monthly basis, obviously that is a very small number and one would hope this means favourable treatment. I always pity the LO HON's even more than usual because if one is unlucky enough to fly many domestics there is zero potential to gain any HON miles given the one class cabin.
Seat blocking should be working fine and you can choose the most forward rows on the domestic flight, which on the Dash, are typically blocked until OLCI even if you have the fare class for ASR.
You should be driven to the aircraft by service called "LOT Limousine" on the same basis in the LH hubs, ie, if it would be a bus (or to use obfuscating Lufty language an "Outside Position".) That's 100% guaranteed if its a Dash, less so the larger the aircraft, some KRK are B734 and B738. They have a new fleet of Volvo XC60 (I think) for this. You
should be collected if you arrive into Warsaw on the same terms. I've only seen how they deal with Anna Maria Anders but she is also naturally premium. So, you're really our guinea pig for this as a normal HON.
You can ask at the desk for a LS handling agent to escort you to the gate even if you have a airbridge position but it would be kinda pointless. Indeed, if you do end up with a bus position and there is no escort then do ask at the reception and it should be arranged for you.
All this is in theory
