AirMillion are great for long trips and planning, but the ICAO half-million is usually a good idea as well, at least for anywhere you're likely to be landing or manoeuvring. Or, use an electronic system on a GPS with those charts, and an AirMillion as a paper backup - that works well enough.
I don't recognise the LR and LU designations you mentioned -what part of the world do you want charts for?
