Very good points Rich. As for PPT - it was on my list of big vacation spots, but I checked all the time for availability and nothing ever worked. I could never find both the flight over and the flight back. With there being limited service, you could easily get stuck. Be careful about that.
As for Australia, Perth was a problem because there is limited 3 class service (3 or 4 days a week) and only one of those matched up to where you could arrive and return on the same day.
Rich....does DAR have First service. I don't think I ever looked into that.
