“Shuttle” is doing a lot of work in that search. It covers three genuinely different services with different costs, and people frequently book the wrong one.
Here is what each actually is. A Boulder airport shuttle might mean any of them, and the right answer depends entirely on your trip.
The Three Options
| Public bus | Shared shuttle | Private car | |
|---|---|---|---|
| You travel with | The public | Other passengers | Your own party |
| Route | Fixed stops | Several drop-offs | Direct |
| Schedule | Timetable | Set departure windows | Your flight time |
| Door to door | No | Usually | Yes |
| Priced | Per person | Per person | Per vehicle |
| Flight delay | You miss it | Depends on the operator | Tracked, adjusted free |
That last row is where the three diverge most, and it is the one people discover at eleven at night.
The Public Bus
Boulder has a direct RTD service to Denver International, and it is genuinely good value. Fixed stops, fixed timetable, a few dollars per person.
It suits a solo traveller with a carry-on and a midday flight. Check current fares and timetables at RTD — our full bus comparison covers when it is the better call.
The Shared Shuttle
A van collecting several unrelated parties and dropping each in turn. Priced per person, so cheaper than a private vehicle for one or two people.
The trade is time and control. You travel on their window rather than yours, and you may be the fourth drop-off on a loop. For a 6am flight or a tight connection that is a real risk.
The Private Car
One vehicle, your party only, direct, timed to your flight.
Our Denver airport car service is a flat $270 per vehicle — not per person, which is the detail that changes the comparison entirely.
| Travelling together | Private car, each |
|---|---|
| 1 | $270 |
| 2 | $135 |
| 4 | $67.50 |
| 6 | $45 |
| 12 | Group rate |
At one passenger a shared option wins comfortably. At four the gap narrows sharply, and at six a private vehicle is frequently competitive with per-person pricing — while being direct and timed to your flight.
Which to Book
Public bus — one person, carry-on, midday flight, clear weather, near a stop.
Shared shuttle — one or two people, relaxed timing, happy to share and wait.
Private car — two or more people, an early or late flight, luggage or ski gear, bad weather, a connection you cannot miss, or anyone travelling who needs help.
We would rather tell you to take the bus when the bus fits than win a booking that was not worth making.
What the Flat Rate Includes
- Live flight tracking with automatic pickup adjustment.
- Free wait time — 45 minutes domestic, 60 international, from wheels-down.
- All taxes and fees.
- Free child seats, fitted before pickup.
- Free cancellation up to 24 hours ahead.
- No surge — the same rate at 3am, in a storm, on a holiday.
Curbside collection is free; meet-and-greet at baggage claim is $135 — our meet and greet page covers when that is worth it.
Where Private Cars Collect
Not the rideshare zone and not the bus bays. Collection is from Level 5, Island 2 outside the Jeppesen Terminal — Door 511 east, Door 506 west.
Dispatch confirms your door once you land. Terminal information is published by Denver International Airport.
The Vehicles
| Vehicle | Photo | Guests | Luggage |
|---|---|---|---|
| GMC Yukon XL |  | 6 | 6 bags |
| Mercedes-Benz Sprinter |  | 12 | 12 bags |
| Ford Transit High Roof |  | 14 | 14 bags |
Luggage decides the vehicle more than passenger count does — see the fleet page and our gear sizing guide.
If You Want an Actual Shuttle
Worth being clear: we do run shuttle services, just not shared public ones.
A Boulder limo service shuttle means a vehicle held for your group running a loop — hotel to venue, conference to office, wedding guests to a reception. That is covered on our conference page and employee shuttle page. A Boulder limo service loop is booked hourly rather than per trip.
Winter
Every Mayflower Boulder Limo vehicle is four-wheel drive and winter-compliant year-round, and dispatch monitors COtrip through storm cycles.
A snowy morning is when a fixed timetable costs you a flight and a tracked private booking does not. Our winter storm page explains what we do before you ask.
