Thanks Nick and Rhinochaser for the tips!
There are two reasons I've included Aeropostal (and pushed up the cost and time factor for the trip).
Firstly - it will only cost me £400 to do Aces, Saeta and Taca Peru in June, as I intend to use Worldperk or Flying Dutchman points to 'position' out there.
Secondly, I was worried that the 'Nica' qualifying flight MGA - MIA was only being considered for the 1 million mile bonus, and not for the 100k or 500k. This was raised earlier in the thread, and there was no definitive answer as to whether LatinPass would accept this flight. It does state in the rules that MGA - MIA would qualify Nica for the 1 MILLION mile bonus which some have interpreted to mean not for the 500k.
In the event that I wasn't able to go back to go for the million, it would be devestating to know that I had invested so much time, effort and money only to find that I didn't qualify for the 500k!
In relation to Saeta and Aces - I guess I'll just have to keep an eye on the board to see if Saeta does indeed resume operation.
