So I'm flying from Vancouver, Canada and have two main options - I can pay $1600 Canadian for a total of 28 hours travel time to Cairns or $935 for 40 hours of travel time. This is only for the way there! Is it worth it to spend the extra 12 hours travelling to save $650+? I've never had that long of travelling time before so I'm looking for advice from somebody who maybe has.. Longest travel time I've had is Paris-Vancouver and that was 16 hours. Thanks in advance!
