I'd be more interested in seeing how the world reacts, observing humanity's final days, knowing their fate and awaiting extinction. I expect chaos would ensue. Personally, I'd just do what I could to make those last days matter, try to experience as much as possible that I haven't. Given how humanity would be by the majority in a state of inconsolable denial and rebellion against their fate, it's likely everything would grind to a halt, and getting a plane anywhere would be a *****.
