Just got this from a Ringer fan in the UK:

Trailer is showing in all Showcase Cinema sites in UK, I know because I work in the Projection Booth at one of the sites (Yes I get to watch it several times a day ). Albeight some prints arrived late due to the trailer having to be put on the front of the Lost Soul’s feature.

We are also getting reports from across the US that matinee showings of ’13 days’ did not have the LOTR Trailer. If that is the case, ask for your money back!
