Just looked at the companion fares to LAX and yes use the fares over a week as there is abig difference between some days but can be done as base fare of $1500 pp ew ex CHC.
Silly me thought what can I get from the provinces - well add another $457.50 pp ew and you can fly from the provinces (SI only). Appears to be a major fault when cost of getting to CHC is 1/3 the cost of CHC to LAX - may need looking at.
