Cost to Drive to Cardiff Airport UK
Driving to Cardiff can be convenient, especially with luggage or several passengers, but fuel is only one part of the real cost. Use this page to estimate your fuel cost, include the return journey, check drop-off and parking costs, and decide whether driving, train, coach or public transport makes more sense.
Cardiff Airport sits around 12 miles south-west of Cardiff city centre, near Rhoose, reached via A4232, with access from the M4 at Junction 33.
The simple answer
The fuel cost of driving to Cardiff depends on your starting distance, fuel price and MPG. A 100-mile trip in a 45 MPG petrol car at £1.60 per litre costs about £16 in fuel each way, or about £32 return.
That is not the full airport cost. You may also need to include the drop-off charge, short-stay or long-stay parking, return mileage, vehicle wear and whether public transport would be cheaper.

Extra costs of driving to Cardiff
These are the costs that often make airport driving more expensive than the fuel estimate.
Cardiff increased its terminal drop-off charge from 1 July 2026, to £4.50 for the first 10 minutes, rising by a further £4.50 for every additional 10 minutes — a real jump from the previous £3 rate.
Car Park 2 offers free parking for up to 20 minutes and is a short walk from the terminal — the better option if you don’t need to stop right outside.
Long Stay 2, the cheapest of Cardiff’s three long-stay car parks, starts from around £84 for 8 days pre-booked – genuinely worth comparing against the £7.20 train-and-shuttle fare for a solo traveller. — Purple Parking gives 12% off automatically through this link (affiliate link).
For drop-offs and pick-ups, the driver usually needs the journey home included.
Tyres, brakes, servicing and depreciation still matter on airport journeys.
Given how quickly the terminal drop-off charge escalates, Car Park 2’s free 20 minutes is worth the short walk for most drop-offs.
Cardiff drop-off and parking checklist
Check this before assuming driving is cheaper than the train, coach or taxi.
Are you dropping off?
Check the current terminal drop-off charge before using the forecourt.
Are you picking up?
Pick-ups usually need short-stay parking rather than the drop-off lane.
Are you parking for a trip?
Compare official airport parking, off-airport parking, taxis, rail and coach before booking — Purple Parking offers 12% off with no code needed (affiliate link).
How much luggage?
Driving may be worth more for families, heavy bags, prams, sports equipment or awkward flight times.
Driving to Cardiff vs train, coach or taxi
The cheapest option depends on passenger numbers, luggage, flight time, parking length and how easily you can reach Cardiff by public transport.
Rail + shuttle bus 905
~43 min from Cardiff Central · £7.20 through-ticket
Trains run to Rhoose Cardiff International Airport station, then the 905 shuttle bus (timed to meet every train, hourly, 7 days a week) covers the final leg to the terminal – all on one £7.20 ticket from Cardiff Central. Unusual for a smaller UK airport to have a real rail link at all.
Driving + parking
Fuel + from ~£84 (Long Stay 2, 8 days)
Usually wins once you’re splitting the cost across 3+ passengers, carrying heavy luggage, or travelling outside the hourly shuttle’s timetable. A lift through the free 20-minute Car Park 2 avoids the £4.50 forecourt charge.

Do not forget the return journey
Airport trips are easy to underestimate because the passenger may only think about their one-way journey.
Passenger journey
The passenger may only travel to Cardiff once.
Driver journey
The driver usually travels to the airport and then back home.
Collection journey
A separate pick-up later may mean another return journey and parking cost.
