And here come the bus - I wonder where it is going?
oops. Its going to the silver parking. These people are creating more congestion on the A38 and more pressure for a South Bristol bypass after all.
And why not? As the advert on the bus says, its 29 quid for a week's parking. The bus charges 6 or 7 pounds one way, 8 return. There is a family return for 20 quid, but that still leaves you with the problem of getting from the bus station to your house, and unless you live in walking-with-luggage distance of one of the halts, that's going to involve another bus or a taxi. Probably a taxi, as that will usually cost less than a bus for a family of four.
Of course people are going to use the airport car parks. And as the airport's business model is based on charging the airlines next to nothing and making money from the added value extras, the money they make from parking, from the bus or from the premium they charge the one permitted taxi company must be a significant profit source to the airline. They like you to drive, they want you to park. It's profitable.
