A colleague is taking his sister-in-law (no railcards or discounts) to Heathrow Airport. Unfortunately he has only booked her advance ticket to London (from Edinburgh).
What would be the cheapest option for an open return from King's Cross to Heathrow avoiding the peak periods? As a caveat the route must also be permissable by a passenger holding a TOCNE priv ticket (from Edinburgh to Heathrow Rail).
TIA.
