Porter Airlines (PD) is widely known as a customer-focused regional carrier based out of Toronto’s downtown Billy Bishop Airport. For many years, its turboprop-driven network emphasized short-haul business travel within Canada and the northeastern United States. However, over the years, the carrier has scaled out of its borders.
Currently equipped with a growing fleet of Embraer E195-E2 jets and new ambitions, Porter is carving out a larger share of North America’s international market.
A close look at its busiest international routes reveals an important expansion centered on key U.S. leisure and business destinations, primarily from Toronto Pearson (YYZ) and, increasingly, Ottawa (YOW).
The busiest international route in Porter’s international portfolio is the high-frequency shuttle between New York LaGuardia (LGA) and Toronto Pearson (YYZ). With an average of 171 monthly flights, over 22,500 seats, and more than 8 million Available Seat Miles (ASMs), this corridor highlights the sheer demand on this route.

From Regional Specialist to International Challenger
Porter’s redefinition as a jet-powered international competitor would have seemed unlikely just a few years ago.
The airline’s historic identity was closely tied to its Q400 turboprops and its boutique passenger experience out of Toronto’s waterfront airport. That model worked well for short-haul domestic flights, but it had limitations in terms of range and capacity.
However, the introduction of the E195-E2 changed everything. With significantly more range and seats than the Q400, these jets opened the door to major U.S. markets and leisure destinations previously inaccessible to Porter.
Alongside the New York–Toronto corridor, Porter now serves major U.S. cities like Las Vegas, Los Angeles, Fort Lauderdale, San Francisco, Orlando, Phoenix, and San Diego. These cities represent an expansion of Porter’s reach, particularly into the western U.S., and are clearly chosen to attract both leisure travelers and high-frequency Canadian flyers accustomed to larger carriers.
What’s striking about Porter’s international schedule is how quickly it has scaled. The Las Vegas–Toronto route, for example, now sees 124 monthly flights and more than 16,000 seats. With over 31 million ASMs, it is by far the longest route Porter operates internationally.

The Florida Front: Targeting Snowbirds and Families
Florida remains a popular destination in Porter’s international expansion. In 2025, three of its busiest international routes involve major Florida gateways: Fort Lauderdale, Orlando, and Fort Myers.
Each of these cities offers consistent seasonal demand, with passenger profiles ranging from retirees and second-home owners to theme park-bound families.
The Fort Lauderdale–Toronto route is one of Porter’s most productive southern links, offering 60 monthly flights, i.e., one daily flight in each direction, and nearly 8,000 monthly seats. With ASMs exceeding 9.6 million, this route competes directly with Air Canada, WestJet, and U.S. legacy carriers.
Porter’s appeal lies in its customer-first philosophy, offering no middle seats, complimentary beer and wine, and onboard Wi-Fi even in economy class, which sets it apart in crowded transborder markets.
Porter’s service from Orlando to Toronto also sees 60 monthly flights. While slightly shorter in distance than Fort Lauderdale, it’s especially popular among families visiting Florida’s world-renowned attractions, and its load factors tend to peak during school holidays and winter breaks.
Meanwhile, Fort Myers, though appearing last on the list with just 8 monthly flights, offers a window into how Porter is testing demand in smaller Florida cities with targeted service during high-traffic seasons.
Porter’s approach to Florida is measured yet ambitious. Rather than flooding the market, it has opted for balanced, high-utilization scheduling. Each route is evaluated not just on potential seat sales but also on route profitability and brand fit, ensuring that service levels can remain high even in ultra-competitive markets.

California Dream and the Long-Haul Push
Among Porter’s newest additions are its West Coast U.S. routes. In 2025, service to Los Angeles and San Francisco from Toronto will become a core part of the airline’s transcontinental strategy.
Both routes operate at a steady 60 flights per month, offering just under 8,000 seats each. But in terms of distance, these routes are long enough for a carrier new to long-haul domestic and international operations.
The San Francisco–Toronto route now produces nearly 18 million ASMs monthly, making it Porter’s highest in this metric. The Los Angeles route follows closely behind with over 17 million ASMs. These numbers suggest strong confidence in West Coast demand and in the capability of the Embraer E195-E2 to perform consistently on longer sectors.
Porter bets that its differentiated product, essentially a business-class experience in an all-economy cabin, can attract flyers who value comfort, space, and service.
The West Coast routes also help establish Porter as more than a regional operator. They are statements of intent, reinforcing its arrival as a legitimate alternative on some of the most sought-after city pairs in North America.

Ottawa’s Supporting Role in International Expansion
While Toronto is clearly the centerpiece of Porter’s international strategy, Ottawa (YOW) is emerging as a significant secondary hub. Three of Porter’s 12 busiest international routes now connect Ottawa with Florida and Las Vegas, including Fort Lauderdale, Orlando, and Las Vegas itself.
Though lower in frequency compared to Toronto departures, these routes show Porter’s desire to diversify its international access points and tap into underserved demand from Canada’s capital city.
The Fort Lauderdale–Ottawa and Orlando–Ottawa routes each offer 38 monthly flights and just over 5,000 seats.
The ASMs being 6.7 million and 6 million respectively highlight the economic value of these routes, especially in the winter months.
Las Vegas–Ottawa, though limited to 14 monthly flights, still generates nearly 4 million ASMs, suggesting Porter sees enough demand to maintain a stable, albeit lean, presence.
Here are Porter Airlines’ Busiest International Routes in 2025:
Rank | Route | Flights | Seats | ASMs |
1 | New York-La Guardia (LGA) – Toronto (YYZ) | 171 | 22572 | 8035632 |

12 | Fort Myers (RSW) – Toronto (YYZ) | 8 | 1056 | 1254528 |

Bottom Line
The presence of routes like San Diego–Toronto and Phoenix–Toronto in Porter’s international network highlights the carrier’s evolving strategy.
San Diego sees 30 monthly flights and nearly 4,000 seats, while Phoenix, with 52 flights, provides over 12.8 million ASMs, yet another high-yield, long-haul transborder route for the airline.
These cities are gateways to the American Southwest, offering year-round leisure travel demand and opening up future opportunities for partnerships or code shares with U.S. carriers.
One trend becomes abundantly clear: Porter Airlines is no longer just a regional carrier. The airline is building an international portfolio with strong frequency, respectable seat capacity, and growing market share in both established and emerging city pairs. It is also rapidly climbing the ranks of competitive relevance, not only through route volume but through passenger experience.
