djrules,
In my opinion, this is not a situation where money should be the deciding factor. If I was in your situation, I would be there in the quickest way possible... and not spend time asking the travel board for advice. Ask yourself "How would you feel if your dad passed away before you got there and you knew you could have been there if you did not choose the money-saving option?"
Get to your DAD!!!! Quickly.
