The 4 routes currently connecting Belgium & the US on a non-stop basis

European capitals are generally well-connected to the United States, with hundreds of flights operating on transatlantic routes. However, just four US cities are presently connected to Belgium's capital, Brussels.

Meanwhile, just three carriers – United Airlines, Delta Air Lines, and Brussels Airlines – have nonstop flights between the two countries, with a total of 294 scheduled flights in December 2024, according to the aviation analytics company Cirium data.

United Airlines operates the most flights between the two countries, dominating the market. Indeed, with 186 flights across three US cities this month, the carrier holds a 63% market share.

1 The Brussels (BRU) to Newark (EWR) route

Number of flights in December 2024: 62

The Brussels Airport (BRU) to Newark Liberty International Airport (EWR) route is among the least frequently served flights on this list, with 62 scheduled round-trip flights this month.

Notably, United Airlines dominates the BRU to EWR route. This comes as no surprise, as Newark Airport is the largest United Airlines hub, serving the New York metropolitan zone.

To operate on this route, the Chicago-based carrier utilizes its fleet of Boeing 787-10 Dreamliners. According to ch-aviation data, the airline's widebody typically accommodates a total of 318 passengers in a four-class cabin layout: 44 in business class, 21 in premium economy, 54 in economy plus, and 199 in economy class. United Airlines presently has a total of 21 787-10s.

2 The Brussels (BRU) to Washington DC (IAD) route

Number of flights in December 2024: 62

A very similar situation arises with the Brussels (BRU) to Washington Dulles International Airport (IAD) route, where United Airlines is the sole operator.

Similar to the BRU to Newark Liberty International Airport (EWR) route, United has 62 scheduled operations between BRU and IAD this month.

The US carrier deploys its fleet of 22 Boeing 777-300ER widebodies, as per Cirium data. Seating up to 350 passengers in a four-class cabin, United's 777-300ER has more capacity than its 787-10s.

The airline's 777-300ER cabin includes 60 business class, 24 premium economy, 62 economy plus, and 204 economy class seats.

3 The Brussels (BRU) to Chicago (ORD) route

Number of flights in December 2024: 62

The Brussels (BRU) to Chicago O'Hare International Airport (ORD) is again solely operated by a single airline: United Airlines. The Chicago-based airline has 62 scheduled round-trip flights in December 2024.

According to Cirium data, United typically deploys its young fleet of Boeing 787-10 Dreamliners, which can accommodate a total of 318 passengers in a four-class cabin configuration. The airline's 787-10 fleet has an average age of 4.5 years.

In addition to the 787-10s, the airline operates a fleet of 12 787-8s and 39 787-9 Dreamliners. It is also currently awaiting deliveries of 149 787-9s, according to ch-aviation data.

4 The Brussels (BRU) to New York (JFK) route

Number of flights in December 2024: 108

The most frequently operated route is between Brussels Airport (BRU) and New York John F. Kennedy International Airport (JFK), with a total of 108 round-trip flights scheduled this month. According to Cirium data, two airlines operate in competition on this route.

Delta Air Lines offers 62 scheduled operations between the two cities, utilizing two types of widebody aircraft on this route.

According to Cirium data, 34 flights are operated with the airline's Boeing 767-400ERs, while the remaining 28 flights use Delta's smaller Boeing 767-300ER widebodies.

ch-aviation data reveals that Delta's 767-400ERs can seat up to 238 passengers in a four-class cabin layout: 34 in business class, 20 in premium economy, 28 in economy plus, and 156 in economy class.

Delta's 767-300ERs accommodate a total of 216 people in a four-class cabin: 26 in business class, 18 in economy plus, 28 in economy plus, and 156 in economy class.

It is worth noting that Delta will launch a new transatlantic route connecting Atlanta (ATL) and Brussels (BRU) during the summer of 2025 as part of its network expansion.

Delta's increased competition might threaten United Airlines' dominance in the European city, which benefits from its cooperation with Brussels Airlines and facilitates onward connections to Africa.

Meanwhile, Brussels Airlines offers 46 flights between Brussels and New York JFK this month.

The airline utilizes its Airbus A330-300 widebody, which can seat up to 294 passengers in a three-class cabin layout: 30 in business class, 21 in premium economy, and 243 in economy class. Belgium's largest airline currently operates a total of 45 aircraft, of which 10 are A330-300s.
