Short answer: a saloon minicab typically takes two large suitcases plus two cabin bags, and an estate takes three to four large cases. If you are near the limit, book the next size up.
The most avoidable problem in airport transfers is a car turning up that physically cannot take your bags. It's avoidable because the information needed to prevent it — how many people, how many cases, anything unusual — takes ten seconds to state when booking, and cannot be fixed at all once the driver is on your doorstep at 05:00.
Here's what actually fits in what.
The realistic capacities
Boot space varies between models, so treat these as working guidance rather than guarantees. When you're near a limit, size up.
| Vehicle | Passengers | Realistic luggage |
|---|---|---|
| Saloon | Up to 4 | 2 large cases + 2 cabin bags, or 3 large cases with a lighter passenger load |
| Estate | Up to 4 | 3–4 large cases + cabin bags |
| MPV / people carrier | Up to 6 | Depends heavily on seats used — with all six seats occupied, luggage space drops sharply |
| Minibus | Up to 8 | 8 passengers with a case each usually needs a dedicated luggage area |
The single most misunderstood point: passenger capacity and luggage capacity compete for the same space. A six-seat MPV carries six people or a lot of luggage — rarely both at full capacity. A vehicle rated for eight passengers assumes those passengers are not each bringing a large suitcase.
Four adults with four large suitcases is not a saloon job, even though a saloon seats four.
The rule that prevents almost every problem
Count people and cases separately, then book for whichever is the binding constraint.
- 2 people, 2 large cases → saloon is fine.
- 4 people, 4 large cases → estate at minimum, often an MPV.
- 4 people, 4 large cases and 4 cabin bags → MPV.
- 6 people with luggage → realistically a minibus, or two cars.

Awkward items, specifically
These are the ones that catch people out, because they don't fit the "how many suitcases" mental model.
Golf clubs. A full bag is long and rigid. One bag usually fits an estate; two or more generally needs an MPV or larger. Mention them explicitly — "one large case and golf clubs" is a different vehicle from "one large case".
Skis and snowboards. Long, rigid, and often impossible in a saloon regardless of how few other bags there are. Always flag these.
Pushchairs and prams. A folded buggy takes meaningful boot space — roughly a large suitcase's worth for a full-size model. Travel systems take more. Our family travel and child seat guide covers the seating side alongside this.
Bicycles. Usually need a vehicle where seats can fold down, and often need the bike partially dismantled. Never assume; always ask when booking.
Pets. A dog takes boot space the bags would otherwise use, so it changes the vehicle in the same way a large case does. Taking a dog in a minicab covers the rules, including the legal position on assistance dogs.
Musical instruments. A cello or double bass may need its own seat rather than boot space.
Wheelchairs and mobility equipment. A folding manual chair fits most boots; a powered chair usually requires a wheelchair-accessible vehicle. See our wheelchair accessible travel guide.
Boxes and flat-pack. House moves and student runs need vehicle dimensions, not case counts. Give rough measurements.
Airport transfers deserve extra margin
Two things make airport runs the highest-risk case for getting this wrong.
Return journeys carry more. People routinely book the same vehicle both ways and come home with duty free, gifts, shopping and a case that no longer closes properly. If the outbound was tight, size up for the return.
There's no recovery time. If an undersized car arrives for a 05:00 departure, there is no realistic fix that gets you to the terminal on time. On a long run like Heathrow to central London or a cross-region transfer such as Manchester Airport to Liverpool, a second vehicle is not appearing at short notice.
If you're carrying enough that the train stopped being realistic, our Elizabeth line vs minicab comparison covers where that line sits.
What to say when you book
Be specific and slightly pessimistic. A useful booking note reads like this:
4 passengers, 4 large suitcases, 2 cabin bags, 1 folded pushchair.
Not this:
4 people with some luggage.
The first lets us assign a vehicle that definitely works. The second is a guess. If you're genuinely unsure whether you're over a threshold, say so — it's a much cheaper conversation before the booking than on the pavement.
Frequently asked questions
Q: How many suitcases fit in a standard minicab? A: A saloon typically takes two large cases plus two cabin bags. An estate takes three to four large cases. Exact space varies by model, so if you are close to the limit, book the next size up.
Q: Can 4 people with 4 suitcases fit in one car? A: Not comfortably in a saloon. Four passengers each with a large case usually needs an estate at minimum, and often an MPV once cabin bags are included. Passenger seats and luggage space compete for the same vehicle.
Q: Do I need to tell the operator about golf clubs or skis? A: Yes, always. Long rigid items do not fit a standard saloon boot regardless of how little other luggage you have, and they determine the vehicle type more than suitcase count does.
Q: Does a pushchair count as luggage in a minicab? A: In practical terms, yes. A folded full-size pushchair takes roughly the space of a large suitcase, and travel systems take more. Mention it separately when booking.
Q: What happens if my luggage does not fit the car that arrives? A: It is a genuinely difficult situation to fix at short notice, particularly for early-morning airport runs. This is why stating your exact luggage at booking matters — the vehicle is assigned based on what you tell us.
Q: Is a 6-seater MPV enough for 6 people with luggage? A: Often not. With all six seats occupied, remaining boot space is limited. Six passengers each with a case usually needs a minibus or two vehicles.
