I get that.
But to whom is LHR such a boon?
Handy for the West End and a night In Town. Despite the £45 taxi fare or the £22 rail ticket.
Otherwise anyone wanting to go to London for business or pleasure is better off tackling it from them South, East or West (Gatwick, Luton, Stansted).
Thiefrow is best enjoyed as a Long Haul connector.
