Bristol Airport sits south west of the city, off the A38 near Lulsgate Bottom, postcode BS48 3DY. It has no motorway of its own: whichever direction you come from, the last stretch is A-road. That single fact explains most of what follows — why 19 miles from Bath can take longer per mile than 36 from Taunton, and why a delay on the approach has nowhere to go.
How far is Bristol Airport from…
Road distances to BS48 3DY. The distances are stable and you can plan on them. The times are not: they are a single sample taken overnight on 02/08/2026 in near free-flow conditions, and they are the best the road will ever do.
| From | Distance | Main route | Free-flow sample |
|---|---|---|---|
| Bristol city centre | 8.7 miles | A38 | 21 min |
| Bath | 19.2 miles | A4, then A4174 | 45 min |
| Taunton | 36.1 miles | M5 to J22, then A38 | 48 min |
| Gloucester | 42.8 miles | M5 to J18, then A4/A370 | 59 min |
| Cardiff | 46.8 miles | M4, M49, then A4/A370 | 1 hr 03 min |
| Exeter | 66.2 miles | M5 to J22, then A38 | 1 hr 18 min |
Do not plan a 06:00 flight off that last column. Those times were measured in the middle of the night with the roads empty. We have deliberately not published a “typical peak” figure, because we have not measured one and inventing one is how people miss flights. Check a live route on the morning you travel and add a margin on top of it.
The approaches, as the airport itself describes them
Bristol Airport publishes its own driving directions, and they are worth following rather than improving on — the signage on the ground matches them. Paraphrased from the airport’s By Car page, checked 02/08/2026:
- From the north on the M5 — leave at junction 18 and follow signs for the airport (signposted A4 and A370 Bristol & Airport). The airport flags that Clean Air Zone charges apply to older vehicles on this route.
- From the south on the M5 — leave at junction 22 and follow signs for the A38. No Clean Air Zone warning attaches to this one.
- From the east on the M4 — at junction 20 join the M5 southbound, exit at junction 18, then A4/A370. Clean Air Zone charges apply to older vehicles.
- From the south east (Bath) — follow the A4 towards Bristol, bear left onto the A4174, then follow airport signs.
- From South Wales — M4 over the second Severn crossing, at junction 22 branch left onto the M49, then the A4/A370. Clean Air Zone charges apply to older vehicles.
For live roadworks the airport points people at one.network. It is worth thirty seconds the night before, particularly for the M5 and the A38.
The A38 approach
The A38 is the direct route from Bristol city centre — 8.7 miles — and it is also the road you join coming north off M5 junction 22. Two things about it are worth knowing before you set off, and both are published rather than folklore.
First, the layby by the airport entrance is not a free drop-off. The airport states that the red routes on the A38 and that layby are the responsibility of the local authority and the police, not the airport. People assume it is a loophole. It is a road policed by someone else.
Second, from the city-centre end, the A38 route starts inside Bristol’s Clean Air Zone. The airport is not in the zone; the first few miles of that particular route are.
Bristol’s Clean Air Zone — who actually pays
Bristol’s Clean Air Zone has been live since 28 November 2022. The airport is outside it. It only matters if your route runs through central Bristol — which the city-centre A38 route does, and which the M5 J18 / A4 / A370 approach does, which is why the airport attaches its warning to those directions and not to the M5 J22 / A38 one.
Bristol City Council’s published position, checked 02/08/2026:
- £9 a day for private petrol cars, private diesel cars, taxis and vans under 3.5t. £100 a day for HGVs over 3.5t, buses and coaches.
- Charged once per 24-hour period, not per trip.
- Not charged: Euro 4/5/6 petrol (roughly 2006 or newer), Euro 6 diesel (roughly end of 2015 or newer), fully electric and hydrogen vehicles, CVRAS-retrofitted vehicles, and motorbikes.
- The council says more than 88% of vehicles entering Bristol already comply.
Do not take our word for your own car. Check your registration on the GOV.UK vehicle checker — it takes about ten seconds and it is the only answer that counts. Full detail is on Bristol City Council’s Clean Air Zone page.
Where you are actually driving to
“Bristol Airport” is not one destination. If you have booked one of the airport’s own car parks, you are driving to a specific one of five — as at 02/08/2026 the airport lists Silver Zone, the Multi-Storey, Meet & Greet, Short Stay and Mid Stay — and they are not all in the same place or on the same postcode. Silver Zone is BS48 3DW; Short Stay is BS48 3AQ.
If you have booked with an off-airport operator, you are driving to their compound and not to the terminal at all. Check the address on your booking confirmation before you set off, and put that in the satnav rather than “Bristol Airport”. It is the single most common way people lose fifteen minutes they did not have.
If someone is dropping you off instead
Being driven is a real alternative to parking, and it is worth pricing properly rather than assuming it is free. Bristol Airport’s Drop Off & Pick Up Car Park — the one almost everyone still calls Drop & Go, renamed and moved into the Transport Interchange on 16 July 2025 — is charged by the minute at the gate. On the airport’s own prices page, correct on their site on 30 July 2026:
| Duration | Gate price |
|---|---|
| Up to 10 mins | £8.50 |
| 10 to 20 mins | £10.50 |
| 20 to 40 mins | £13.00 |
| 40 to 60 mins | £30.00 |
| 1 to 2 hours | £60.00 |
Maximum stay two hours, fully cashless, ANPR on the way in and card on the way out. Those figures moved on 5 January 2026, when the airport put the 10-minute rate up from £7 to £8.50 — about 21%, with roughly a fortnight’s notice, which it attributed to its business rates bill more than doubling. Assume it will move again and check the airport’s current tariff rather than trusting the number above the day you travel.
The free option nobody knows about: the Waiting Zone near the Car Rental Centre (BS48 3DW) gives one hour free, then £20 an hour. A bus runs from there to the Transport Interchange. The catch is real, though: no return within 30 minutes. ANPR logs entry and exit and the same vehicle coming back inside half an hour gets an automatic Penalty Charge Notice. Circling between the two is exactly the thing that catches people out.
And if a drop-off turns into two round trips because a flight slips, the arithmetic changes completely — a return drop-off from Bath is four legs of nineteen miles. That is the real comparison with parking, not the gate price.
Town by town
Three of the towns in the catchment have a genuinely different journey — different roads, different alternatives, different sums — so they have their own pages:
- Bath to Bristol Airport — 19.2 miles, almost all of it A-road, and the only one of these five towns with a direct airport coach.
- Cardiff to Bristol Airport — 46.8 miles over the Severn, toll-free since 2018, and no direct Flyer route.
- Exeter to Bristol Airport — 66.2 miles up the M5, and the one place where the honest advice is to check your own airport first.
Taunton and Gloucester do not need their own pages, because their journeys are the two approaches already described above. Here is everything that is specific to each.
Taunton — 36.1 miles
The shortest of the Somerset runs and the simplest: M5 north to junction 22, then the A38 north to the airport. It is the same approach as Exeter, thirty miles shorter, and it has the same shape — the motorway does the straightforward part and the A38 does the last of it.
The useful points: this route does not touch Bristol’s Clean Air Zone at any point, which the northern approaches do; and the airport’s Airport Flyer network does not serve Taunton, so public transport means a train to Bristol Temple Meads and then the A1 Flyer, which the airport publishes from £9.50 single. For two people that is four fares plus two rail tickets each way, which is where driving and parking usually starts to make sense.
Gloucester — 42.8 miles
Almost all motorway: M5 south to junction 18, then A4/A370 in on the airport’s signed route. Two things follow from that.
One, it is the approach the airport itself attaches a Clean Air Zone warning to — the A4/A370 run in from J18 goes through charged territory, so an older diesel adds £9 to the trip in each direction on separate days. Check the registration before you set off, not after.
Two, the whole trip hangs on one stretch of motorway. If the M5 is disrupted between Gloucester and junction 18 there is no quick way round it, so it is worth thirty seconds on one.network before you leave rather than finding out on the hard shoulder. There is no Flyer route from Gloucester either — public transport means rail into Bristol and then the A1.
Parking, once you get there
Everything above is the drive. What you do with the car at the end of it is a separate decision, and we have written it up properly:

- Cheapest Bristol Airport parking in 2026 — where the money actually goes.
- Meet & Greet, explained — if you would rather hand the keys over at the terminal than drive into a car park at 04:30.
