Published on November 29, 2025

United Airlines joins Air Canada, Delta Air, WestJet, and American Airlines in the most explosive transatlantic expansion ever. This bold move marks a defining moment in the airline industry. Together, these giants are reshaping the skies over the Atlantic. Their combined efforts signal a new era in global travel. With each airline increasing their European presence, the competition has never been fiercer.

United Airlines, along with Air Canada, Delta Air, WestJet, and American Airlines, is aiming to dominate the transatlantic market like never before. This ultimate airline power play will bring more routes, better services, and enhanced experiences for travelers. As they unite, passengers can expect unprecedented choices and lower fares, making transatlantic travel more accessible than ever.

United Airlines: The Leader of the Transatlantic Skies

United Airlines is the undisputed leader when it comes to transatlantic flights. With over 30 destinations across Europe, it is widely considered the largest carrier flying between North America and Europe. The airline has consistently maintained a vast network that reaches key business and leisure destinations, offering multiple daily flights to cities such as London, Paris, Frankfurt, and Rome.

While official statistics from United Airlines are sparse, industry analyses suggest that the airline’s dominance is unquestioned. This means that whether you’re traveling for business, leisure, or just to see the sights, United’s robust European network makes it the top choice for many passengers flying across the Atlantic. As such, its vast network of services allows the airline to continuously increase its capacity, attracting millions of travelers annually.

Air Canada: Second Place, But Not for Long

Air Canada, with 28 European destinations as of the summer of 2025, is looking to close the gap with United. According to reports from Aviation Week based on OAG analysis, the airline is currently operating 5.8 million seats to Europe, an increase from 5.49 million in 2024. While it trails United Airlines in the total number of destinations, Air Canada is set to become a major player in the coming years, claiming the second-largest transatlantic network by destinations.

The airline’s growth is further supported by its expanding fleet and strategic route additions. In the near future, Air Canada plans to build on its already impressive offerings, and by the summer of 2026, it will officially be North America’s second-largest transatlantic network, right after United. With routes that span major cities like London, Paris, and Frankfurt, as well as leisure destinations like Rome and Barcelona, Air Canada has firmly established itself as a key competitor in the transatlantic market.

Delta Air Lines: A Strong Challenger

Delta Air Lines is another powerful competitor in the transatlantic market, with “nearly 30” destinations in Europe. The airline’s summer 2026 schedule includes over 650 weekly flights to Europe, offering a competitive mix of major city connections, regional hubs, and popular tourist spots. While Delta’s European network is slightly smaller than United’s and Air Canada’s, it is still a formidable contender, with strategic services to cities like Amsterdam, London, and Paris.

Delta has been actively expanding its international reach, and its European presence is one of the largest in North America. Although the airline falls short of United’s dominance, it still represents a significant player in the European market. Passengers can expect a high level of service, reliability, and frequent flyer benefits when choosing Delta for their transatlantic travel needs.

WestJet: A Smaller But Growing Player

Unlike the industry giants, WestJet offers a more modest selection of transatlantic destinations. The airline currently flies to nine European destinations from Halifax, including newly added routes to Lisbon, Madrid, and Copenhagen. WestJet’s transatlantic network has been steadily growing, with additional flights to popular destinations such as Barcelona, Amsterdam, Dublin, and London.

While WestJet’s overall European reach doesn’t compare to the larger players like United or Air Canada, its growing presence in the transatlantic market is noteworthy. The airline offers an affordable option for travelers seeking to connect to major European cities from Canada. WestJet’s focus on increasing its presence in Europe suggests that the airline will continue to expand its reach in the coming years, especially as demand for European travel continues to rise.

American Airlines: A Major Player with Limited Information

American Airlines is another significant force in the North American transatlantic market, with an estimated 20–25 destinations in Europe. However, unlike some of its competitors, American Airlines has not released a single official summary of its transatlantic network. This makes it harder for analysts to track its exact European reach.

Despite the lack of detailed information, industry sources estimate that American Airlines serves a significant number of European cities, with new routes to destinations like Prague and Budapest. While American Airlines may not have as many destinations as United or Delta, its European offerings are still substantial, and it continues to play an essential role in the North American-European flight market.

A Growing Demand for European Travel

As the world slowly recovers from the pandemic, demand for travel to Europe has surged, driving North American airlines to further expand their routes. This increase in demand is particularly notable during the summer months when Europeans and North Americans flock to each other’s continents for vacations, business trips, and cultural exchanges.

Airlines are capitalizing on this boom in tourism by launching new routes, increasing frequencies, and offering competitive pricing to attract travelers. United Airlines, for example, has consistently increased its seat capacity across the Atlantic to meet rising demand. Likewise, Air Canada, Delta, and American Airlines have all announced plans to enhance their European networks, further intensifying the competition.

What Does This Mean for Travelers?

For travelers, this growth in transatlantic routes means more options, better connectivity, and potentially lower fares as airlines compete for business. With a broader range of European destinations now available, passengers can choose from an extensive list of cities, whether they’re looking to visit cultural hubs like London and Paris, explore coastal gems like Barcelona, or enjoy the charm of smaller cities like Vienna or Geneva.

Additionally, airlines are investing in better customer experiences with improved in-flight services, loyalty programs, and travel amenities. These efforts are designed to make long-haul flights more comfortable and convenient for travelers, making it easier to cross the Atlantic and experience Europe’s rich history, culture, and landscapes.

The Future of Transatlantic Competition

As the global tourism sector continues to rebound, the competition between North American airlines for supremacy in the transatlantic market is expected to intensify. With each airline vying for dominance, passengers can look forward to more route options, competitive pricing, and enhanced travel experiences.

United Airlines will likely remain the leader for the foreseeable future, but Air Canada, Delta, and other players like American Airlines and WestJet are closing the gap. Each airline has its strengths, whether it’s United’s vast reach, Air Canada’s expanding network, Delta’s reliability, or WestJet’s growing presence in Europe.

A Bright Future for Transatlantic Travel

The transatlantic flight market is becoming increasingly competitive, with North American airlines expanding their networks to meet the growing demand for European travel. United Airlines remains the leader, but Air Canada, Delta, and other carriers are working hard to carve out their own niches in this dynamic and lucrative market.

Travelers stand to benefit the most from this competition, as airlines offer more destinations, better services, and lower fares. As the transatlantic network continues to evolve, North American airlines will undoubtedly play a significant role in shaping the future of global air travel.
