Holidaymakers heading on breaks through Heathrow Airport can book their getaways early in the summer to avoid paying an extra £25 charge.
The West London travel hub will be within the expanded Ultra Low Emission Zone from August 29.
That means anyone who is planning to drive to the airport will have to pay £12.50 each way, on top of parking that costs from £6 for half-an-hour drop off parking, and potentially several hundred pounds for a week.
