'Regional' flights 'within' WA is the basis of the enquiry, I think.
i.e. It can cost 'an arm' for a flight to Albany, Esperance, Kal or Broome at, say, Easter, than a week prior to or after......
Why? That is the question.
You may quote 'supply and demand' - but - there is something just not quite 'right' at times....
No cheers, Nope, None at all.....
