I’m on my phone right now travelling, so I can’t make a substantive post. I was informed (their original source was on a Flyertalk post) that Lufthansa First Class availability is WIDE open in 2016, using the United search tool. This is special because Lufthansa First Class is usually only released 14 days or so before departure. I don’t know if this is bookable, or if it is bookable using Aeroplan. Once I get access to computer, if it’s still live, I’ll write more.
Update 1: it’s bookable on Aeroplan!
