The bus to Hamilton airport is the HSR A Line Express, Route 20. In the timetable we reviewed (effective 27 April 2025) it ran seven days between Waterfront at Pier 8, West Harbour GO, James and King, Mohawk College, Upper James and the YHM terminal, taking roughly 40 minutes from James and King. Check hamilton.ca/hsr for current times; a sedan is $90-115.
Bus to Hamilton airport: the route in one paragraph
Hamilton's only direct public bus to John C. Munro Hamilton International Airport is the A Line Express, Route 20, run by the Hamilton Street Railway. It starts at the waterfront at Pier 8, runs south on James Street North past West Harbour GO and through downtown, climbs the escarpment by the James Mountain Access, stops at Mohawk College's transit terminal, then follows Upper James Street past the Linc, Stone Church and Rymal to the Mountain Transit Centre, Aeropark and the airport terminal. The airport's own ground transportation page lists the same service. Our Hamilton airport YHM guide covers everything else about the airport; this post is the bus in detail.
The timepoints, north to south
The HSR timetable lists these main timepoints. Other stops sit between them.
- Waterfront and Pier 8
- James and West Harbour GO
- James and King (downtown, a short walk from Hamilton GO Centre)
- Mohawk College Transit Terminal
- Upper James and Mohawk
- Upper James and Rymal
- Mountain Transit Centre (a park and ride)
- Aeropark and Glanair
- Airport Passenger Terminal
The map also marks the Canadian Warplane Heritage Museum along the Aeropark section, which makes the route handy for museum visits as well as flights.
How long the bus takes
In the April 2025 timetable, weekday trips from the airport terminal reached James and King in roughly 37-42 minutes and West Harbour GO in roughly 43-50 minutes, depending on the time of day. Southbound, James and King to the terminal took roughly 39-44 minutes. Weekend trips were slightly quicker. By comparison, a car from downtown takes 20-25 minutes for the 15 km, because it uses the Linc rather than stopping along Upper James.
First and last trips: the numbers that matter
For a flight, frequency matters less than the first and last buses. In the timetable we reviewed:
- Weekdays: the first southbound trip reached the airport at about 6:01 a.m.; northbound trips left the terminal from 5:25 a.m., with late short trips to the Mountain Transit Centre after midnight.
- Saturdays and Sundays: the first southbound arrival at the airport was about 5:50 a.m., and northbound trips left the terminal from 5:25 a.m.
- Sunday evenings ended earlier than weekdays, with the last full northbound trip leaving the terminal before 11:00 p.m.
These times change with each HSR service period and on holidays. Treat them as a guide to the shape of the service and confirm the exact trips for your date on the HSR site.
How often it runs
Frequency varied through the day in the April 2025 timetable. Weekday rush hours had buses about every 10 minutes; midday service was roughly every 10-20 minutes; evenings dropped to about every 30 minutes. Weekends ran about every 15-30 minutes. That is good service for a small airport, but an evening arrival can still mean a half-hour wait at the stop.
Paying the fare
HSR fares, payment methods and transfers are set by the city and change from time to time, so we do not print them here. HSR accepts payment methods listed on its site, including the PRESTO card used across the region. Visitors arriving from abroad should check the options before landing, since the airport stop is not the place to discover your card is not accepted.
Luggage on a city bus
The A Line uses regular city buses, not coaches. There is no under-floor compartment; everything rides with you. A carry-on and a backpack are easy. One large suitcase is manageable outside rush hour. Two large cases, a stroller and a car seat will crowd the aisle and are hard to control on the escarpment climb. If you are travelling heavy, plan the bus for off-peak trips, or book a car for the airport leg.
Who the bus suits
- A solo traveller or a couple with light luggage.
- Someone living along James Street, near Mohawk College or on the Upper James corridor.
- A daytime flight comfortably inside the timetable.
- Students heading to Mohawk's Fennell campus from the airport.
- Staff working at the airport business park.
Who should book a car instead
- Families with children, car seats and several suitcases.
- Anyone on a first-wave morning flight who cannot risk a missed bus.
- Late-evening arrivals, especially on Sundays.
- Travellers from Ancaster, Dundas, Stoney Creek, Waterdown or Burlington, who would need a second bus first.
- Older passengers or anyone with limited mobility.
A HamiltonLimo.net business sedan from downtown is $90-115 all-in plus HST for 15 km and 20-25 minutes, door to curb. An executive SUV for six is $150-190.

Connecting to GO Transit and VIA
The A Line links the airport to the regional network at two points. Downtown, James and King is a short walk from Hamilton GO Centre on Hunter Street. At the north end, it stops at West Harbour GO on James Street North. From either, GO Transit services run toward Burlington and Toronto, and some trips toward Niagara. VIA Rail travellers use Aldershot station in Burlington, which is a separate connection. Our pages on Hamilton GO Centre and West Harbour GO explain how our chauffeurs meet passengers at each.
The Glanbrook Trans-Cab
The timetable also mentions the HSR Trans-Cab, which extends several routes, including Route 20, into the Glanbrook area. It is booked by phone through the city's contractor. If you live in Binbrook or rural Glanbrook, check the city's Trans-Cab information to see whether it connects with the A Line for your trip. For a direct ride, our Binbrook and Glanbrook page lists fares to the airport.
Winter on the A Line
The bus climbs the escarpment on the James Mountain Access, the same kind of road that slows first in snow and freezing rain. Delays are common on storm days, so leave a margin, or switch to a car if a storm is forecast before an early flight. Check Ontario 511 and HSR service alerts on bad-weather mornings.
Visiting the Warplane Heritage Museum by bus
Because the route passes the museum area near Aeropark, some visitors use the A Line for a museum day. Check the stop nearest the museum entrance on the HSR map and the museum's own hours before you go. For a group, or for combining the museum with other stops such as the waterfalls or Dundurn, an hourly chauffeur is easier: a business sedan is $120-145 per hour with a 3-hour minimum. Our Canadian Warplane Heritage Museum page has visit details.
Mix and match: bus one way, car the other
Many travellers use the bus in daylight on the way out and book a car home after a late landing, when the bus is running every half hour or not at all. You pay one fixed fare and skip the evening wait. Our post on how to get to Hamilton airport without a car compares every option from across the region, and Hamilton airport parking vs a drop-off covers the drivers' side.
Where the bus stops at the terminal
The timetable's last stop is the Airport Terminal Entrance, and the map shows the bus looping on Airport Road at the passenger terminal before heading back north. Arriving passengers walk out of the Arrivals doors to find it; departing passengers step off close to the building. Taxis use their own zone across from Arrivals and rideshare the west end of the curb, so the bus stop is separate from both. Ask at the terminal information desk if you cannot see the stop, and check the HSR's real-time information before you walk out into the weather.
Planning a departure on the bus: a worked example
Suppose you live near Mohawk College and have a 9:30 a.m. domestic flight. Work backwards: your airline's recommended arrival time, a margin for security, then the bus timing. In the April 2025 weekday timetable, trips left Mohawk College Transit Terminal roughly every 10 minutes in the morning peak and reached the terminal about 25 minutes later. A trip arriving around 7:45 a.m. would give a comfortable margin. Always choose the trip before the one you think you need; a single late bus should not decide whether you fly.
Planning an arrival on the bus: a worked example
Now reverse it. You land from a sun destination at 10:40 p.m. on a Sunday. Customs, bags and the walk out take 30-60 minutes. By the time you reach the stop, Sunday service may already be ending for the night. That is the classic case for a booked car: the chauffeur tracks the flight, waits up to 60 minutes after landing on an international arrival at no charge, and drives you home in 20-25 minutes from downtown's direction. The late-night picture is covered in our post on Hamilton airport hours and late flights.
Accessibility on the A Line
The city publishes accessibility information for HSR buses, and for its specialized transit service, on its own site; check it before you travel if you use a mobility device. For airport trips, remember that assistance inside the terminal comes from your airline, not the bus. If a passenger needs door-to-door help with bags, a booked car is often simpler; our chauffeurs fold and stow wheelchairs and walkers for passengers who can transfer to a seat.
Booking a car when the bus will not work
Book on HamiltonLimo.net's own reservation engine: enter your address, YHM and the flight number, choose the vehicle and see the fixed all-in fare with HST shown separately before you confirm. No app and no marketplace commission. For current airline routes, check flyhamilton.ca.
