The three hour rule, in plain figures
Nothing at Heathrow is booked for less than three hours, £700. Her journey out to you comes out of those three hours; it is not stacked on top of them. Because the airport lies far outside the two central fare zones, her taxi there and back is costed at the moment you book, and the desk quotes that figure alongside the fee before you say yes. One number, agreed in writing, and nothing left to talk about when she knocks.
Longer bookings climb the same tariff as in town. For guests with an early flight, the usual answer is the overnight: ten hours, £1,800.
