Vehicle choice at Heathrow matters more than headcount alone. A standard saloon suits one or two passengers with a case each, a pre-booked estate or MPV suits a family with several large cases, and a minibus or Mercedes V-Class suits a group of six to eight. Black cabs from the rank seat up to five people but have more modest boot space. Checked August 2026.
Vehicle classes at a glance
| Vehicle | Typical passengers | Luggage, as a guide | Best for |
|---|---|---|---|
| Black cab (rank) | Up to 5 | Modest boot, around 2 to 3 large cases | Solo and couple travellers with light bags |
| Saloon (pre-booked) | Up to 3 or 4 | Around 2 to 3 large cases | Couples, solo travellers |
| Estate | Up to 4 | Around 3 to 4 large cases | Families where everyone has one case |
| MPV, 6 seats | Up to 6 | Around 4 to 5 large cases | Families with a pushchair or extra kit |
| Executive (Mercedes E-Class) | Up to 3 | Around 2 to 3 large cases | Business travellers who want the space |
| Minibus / Mercedes V-Class, 7 to 8 seats | 7 to 8 | Around 6 to 8 large cases | Groups |
These are general guides rather than fixed rules, since boot space varies between individual cars. If you're travelling with a full set of large cases, it's worth confirming capacity with the operator when you book.
Why headcount alone doesn't tell you what you need
A car that seats four people doesn't necessarily have room for four large suitcases. Four adults each bringing a case is usually an estate or MPV job rather than a saloon, because the boot fills up long before the seats do. This catches out groups who book by passenger number without thinking about the boot.
The vehicle classes pre-booked operators offer
Pre-booked operators serving Heathrow typically offer a similar range of vehicle classes: a standard saloon for couples and solo travellers, an estate for families who each have a case, an MPV for larger families or those with a pushchair, an executive Mercedes E-Class for business travellers, and a minibus or Mercedes V-Class for groups of up to eight. You choose the class when you book, and the price reflects the vehicle. For fixed fares on specific routes, see the taxis page and the routes page.
Black cabs: seats more than it stores
If you're heading straight to the rank rather than pre-booking, remember that a black cab seats up to five but its boot is smaller than an equivalent-sized minicab. A single traveller or a couple with cabin bags is usually fine, but a family of four with a full set of holiday luggage may find the boot tight, and a second cab or a pre-booked larger vehicle can be the more comfortable choice.
Awkward and oversized items
Golf clubs, ski bags, pushchairs, wheelchairs and boxed items generally fit in a pre-booked car, but they change which vehicle class you need. It's worth telling the operator what you're carrying when you book, so the right size car is sent, rather than discovering a mismatch at the terminal.

Frequently asked questions
How many suitcases fit in a Heathrow taxi? As a guide, a saloon takes around two to three large cases, an estate or MPV around three to five, and a minibus or Mercedes V-Class around six to eight. Confirm with the operator when you book if you're carrying a full set of luggage.
Can four people with four suitcases fit in one Heathrow taxi? Not comfortably in a saloon. Four adults each with a large case are better suited to an estate or MPV, since the boot fills up before the seats do.
Do black cabs at Heathrow have enough boot space for a family? A black cab seats up to five but has a more modest boot than an equivalent-sized minicab, so a family with a full set of holiday luggage may prefer a pre-booked estate or MPV, or two cabs.
Can a Heathrow taxi carry golf clubs, skis or a wheelchair? Generally yes, but these items change which vehicle class you need. Tell the operator when you book so the right size car is sent.
