I would like to try and manage smartly my eUp credits for the rest of the year. As such I am curious to hear what is the general feeling regarding the success rate for eUpgrading to PY on intl routes. I'm not asking about specific dates, I'm just after a general opinion about which routes can be harder to eUp, which ones seem easier, any difference on the outbound vs inbound and so on, TATL being especially of interest. Of course I am also aware that load factors can vary widely depending on the time of the year.
