Alliance and partnership
Air Canada and United are both founding members of Star Alliance. This means you can earn and redeem miles across both airlines, enjoy reciprocal elite benefits, and access each other’s lounges when your status or cabin allows.
If you hold United MileagePlus status, you can typically access Air Canada Maple Leaf Lounges on eligible itineraries, and Aeroplan elites can access United Clubs and partner lounges when flying internationally.
Despite the partnership, they compete head‑to‑head on many Canada–US transborder routes and some transatlantic services. The alliance makes interlined bookings and codeshares straightforward, so mixed‑carrier itineraries are common.
Route networks and hubs
Air Canada’s primary hub is Toronto Pearson (YYZ), with major secondary hubs in Montreal (YUL), Vancouver (YVR), and Calgary (YYC). It serves 220+ destinations worldwide and dominates domestic Canadian traffic, plus strong transatlantic links from Toronto and Montreal.
United’s hubs include Chicago O’Hare (ORD), Houston (IAH), Newark (EWR), Denver (DEN), Los Angeles (LAX), San Francisco (SFO), and Washington Dulles (IAD), covering 300+ destinations globally and offering deep domestic US connectivity.
For travel within Canada, Air Canada is usually the default choice. For US domestic trips, United’s network is far stronger. On US–Canada transborder routes, both can be competitive; the better option often comes down to which hub (e.g., YYZ vs EWR) is more convenient for your connection.
Economy Class: seats, comfort, and restrictions
Air Canada Economy on newer Boeing 787 and Airbus A220 aircraft is notably comfortable. The A220 is quiet with large windows, and long‑haul aircraft generally offer seatback entertainment, power outlets, and complimentary meals on qualifying routes. Typical seat pitch is about 31–32 inches.
United Economy has improved with refreshed cabins, larger overhead bins, and seatback screens on many aircraft, plus power outlets. However, United Basic Economy is one of the most restrictive fares in the industry, often banning full‑size carry‑on bags and limiting changes and seat selection.
On long‑haul flights, both airlines’ 787 Economy cabins are competitive. Air Canada’s 787 experience is often rated slightly higher on transatlantic routes, but the difference is modest and aircraft type matters more than brand alone.
Premium Economy: Air Canada vs United
Air Canada’s Premium Economy (often branded as Comfort Class in some materials) is available on many long‑haul international routes. It offers wider seats with more pitch and recline than standard Economy, upgraded dining, priority boarding, and dedicated check‑in lanes.
United Premium Plus is United’s Premium Economy product. It features wider seats with extra recline, enhanced multi‑course meals, larger amenity kits, and upgraded bedding on overnight flights.
Both products are strong and a worthwhile upgrade from standard Economy on long flights. United Premium Plus is often considered to have a slight edge in seat width and bedding quality, especially on overnight long‑haul routes.
Business Class: Air Canada Signature vs United Polaris
Air Canada Signature Class is the airline’s long‑haul Business Class. It features fully flat beds with direct aisle access in a 1‑2‑1 configuration. Newer seats include privacy screens (though not full doors), Givenchy amenity kits, and menus developed with Canadian chefs.
United Polaris is United’s flagship international Business Class, also with fully flat beds and direct aisle access in a 1‑2‑1 layout. Highlights include Saks Fifth Avenue bedding, multi‑course dining, and premium amenity kits. Dedicated Polaris Lounges at hubs like Chicago (ORD) and San Francisco (SFO) are among the best in North America.
Both Business Class products are competitive, but United Polaris is generally regarded as slightly stronger overall, particularly because of the Polaris Lounge experience and consistently excellent bedding. Air Canada Signature is still an excellent choice, especially on newer aircraft.
Baggage policies and fees
Air Canada Economy typically allows one standard carry‑on plus one personal item. Checked bags are charged on most Economy fares within North America, with common fees around $32 CAD for the first bag and $53 CAD for the second on many domestic routes, though exact fees vary by route and fare. Many Aeroplan credit card holders receive a free first checked bag.
United Economy usually charges $35 USD for the first checked bag and $45 USD for the second on most domestic US routes, with international fees varying by destination and fare. United Explorer and some co‑branded cardholders get a free first checked bag. United Basic Economy passengers often cannot bring a full‑size carry‑on, which is a major differentiator.
Overall, checked bag fees are broadly similar when converted between CAD and USD. The biggest practical difference is United’s restrictive Basic Economy carry‑on rules, which can add cost and inconvenience if you travel with more than a personal item.
Loyalty programs: Aeroplan vs MileagePlus
Air Canada Aeroplan is widely regarded as one of the most valuable loyalty programs in North America. After its 2020 overhaul, Aeroplan introduced flexible award charts, eliminated carrier surcharges on Air Canada flights, and enabled online booking for most Star Alliance partners. It also allows stopovers on one‑way awards for an additional mileage cost. Status tiers range from Aeroplan 25K up to Super Elite 100K.
United MileagePlus is also strong, especially for Star Alliance partner awards. It uses dynamic pricing for United‑operated awards but maintains more predictable pricing on many partner awards. MileagePlus miles typically expire after 18 months of inactivity, though this can be reset with qualifying activity.
For 2026, Aeroplan is generally considered the better program for Star Alliance redemptions thanks to no carrier surcharges on Air Canada flights and flexible routing rules. MileagePlus remains attractive, particularly if you fly United frequently within the US and value its elite benefits and upgrade options.
On‑time performance and reliability
Both airlines have solid operational records, but performance can vary by season and hub. Air Canada’s main hub at Toronto Pearson (YYZ) faces challenging winter weather and congestion, which can lead to seasonal delays and longer connection times.
United’s diversified hub network across the US provides more rerouting options when one hub experiences disruptions. In recent years, United has invested heavily in improving its on‑time performance and reliability, and it competes closely with Air Canada on transborder routes.
For tight connections, consider both the specific hub and time of year. A winter connection through YYZ or EWR may warrant extra buffer time compared with shoulder‑season travel.
Pricing: transborder and transatlantic
On Canada–US transborder routes, Air Canada and United often price similarly because they operate many of the same city pairs and coordinate schedules through Star Alliance. Sales and competition from low‑cost carriers can tilt prices either way.
Within Canada, Air Canada has more pricing power due to its dominant network, though WestJet and others provide competition on key routes. Within the US, United competes with all major US carriers and low‑cost airlines, which can drive aggressive pricing on some routes.
For transatlantic flights, both airlines offer competitive fares, but the cheapest option often depends on your origin, destination, and connection point (e.g., YYZ vs EWR vs YUL vs SFO). Currency fluctuations between CAD and USD can also influence which carrier appears cheaper when you search. Always compare both on Travorio before booking.
Which airline should you choose?
Choose Air Canada if you primarily fly within or from Canada, want to maximize Aeroplan for Star Alliance redemptions, value the quiet A220 on shorter routes, or are connecting through Toronto (YYZ) or Vancouver (YVR). Air Canada is also a strong pick for transatlantic flights from Eastern Canada.
Choose United if you are US‑based, rely on United’s extensive domestic hub network, want access to Polaris Business Class and Polaris Lounges on long‑haul routes, or already hold MileagePlus status. United is especially compelling for US domestic plus long‑haul combinations.
For many transborder travelers, the decision comes down to schedule, price, and hub convenience rather than a clear quality winner. Because both are in Star Alliance, you can still credit flights to either Aeroplan or MileagePlus depending on which program you prefer.
Flexible payment options on Travorio
When you book Air Canada or United flights on Travorio, you can pay in several flexible ways. In addition to standard card payments, you can pay with Bitcoin, Ethereum, or USDT, or use buy now, pay later options like Sezzle, Klarna, or PayPal Pay Later where available.
