Your routing looks very straightforward. Probably the least contentious that has been posted here in a while! You say it will last "10 - 12 months". That's fine because the maximum validity of any oneworld Exporer ticket is 12 months from date of the first flight!!

1.If you ticket it a PMQ-SCL as a single flight it will count as one segment but you will not be able to stopover in PMC. To stopover you will need to have it ticketed as two separate segments.

2. My last ticket was a mixed of open dated and dated. I haven't had any problems changing dates or adding dates to undated segments. Your choice.

3. AONEX, DONEX, MONEX, are the fare basis.

A=First Class
D=Business Class
M=Economy Class

The X is the number of Continents. e.g a AONE6 is a 6 Continent ticket in First Class and a MONE3 is a 3 Continent in Economy Class.

Are you doing this trip in Business or First? If so you would be better starting in Gibralter as the prices there are much lower than ex-London.
