That isn't the way I read it. I appeared to be reading about the same journey, booked from different locations. There have recently been successful actions against this very practice - I forget the organisation which did the researchm I have a feeling it was a Spanish consumer organisation.
Of course the difficulty is that you have to 'book' a flight from two different locations at precisely the same moment. Of course, if the numbers quoted are exactly the same, except that one is in sterling and the other is in euros, that's a bit of a give-away.
