I’m looking at Qantas flight QFA12 from KLAX to YSSY and the planned track for the flight reaches the left-hand side of the map (presumably the international dateline) and then tracks due east (all the way around the world!) to the right-hand side of the map, at which point it continues on to YSSY. I’m thinking this is probably a simple wrap-around bug with a simple fix (famous last words).
A related feature request: It would be really nice if the map could scroll an unlimited amount in either direction. I guess the need for this won’t exist until asia/pacific flight information becomes available though…
