I'm currently on LH495 YYZ-MUC and then LH1752 MUC-ATH in economy for May/June 2018 on an overall business class trip. I was wondering if this happened to be one of the routes, at least the transatlantic portion, that tends to have availability open up in J. Basically I want to figure if I should be keeping my eyes open for the same route in J, or perhaps another route that goes transatlantic in J. Thanks!
