I know da bomb is not following much logic most times, but this one perplexes me.

I am getting sick of going to to same old UA destinations, so decide to see what it would cost to fly to one of the newer ones - Accra, Africa.

Type SYD-ACC into da bomb and get $US10,246 for April RT lowest coach.

Now even I can see that is insane, so do 2 searches for same dates and get

SYD-IAD $US1,507, and IAD-ACC for $1,235.

Da bomb gives more than 5 times higher.

Now we all know that IAD-LAX-LAS will often price higher than IAD-LAX etc, but how on earth can 2 fares added together get to be 5 or 6 times higher?
