The world’s busiest airline routes in 2024 are largely in Asia

English as the Lingua Franca in Asia

The busiest international flight routes listed by OAG—such as Hong Kong to Taipei,Kuala Lumpur to Singapore, and Seoul to Tokyo Narita— are largely in Asia. These routes connect passengers, businesses, and cultures across borders, often involving pilots and air traffic controllers (ATCOs) who are not native English speakers.

• For pilots and ATCOs, clear communication in English is essential to ensuring safety during high-pressure moments like takeoffs, landings, and navigation through congested airspace. With increased air traffic comes frequency congestion, and that means that pilots and ATCOs need to get their message across faster.  On top of that, misunderstandings caused by accents, non-standard phraseology, or limited vocabulary could lead to significant safety risks.
• For cabin crew, interacting with international passengers requires a strong command of English to address concerns, handle emergencies, and provide exceptional (or barely acceptable) service.
• For engineers, understanding and exchanging technical information in English with international colleagues is key to ensuring maintenance standards are met across borders.

Realities of High-Traffic Routes: The Stakes Are High

1. Hong Kong to Taipei: 6.8 Million Seats (World’s Busiest Route)

This route highlights the immense volume of short-haul international traffic in Asia. With hundreds of flights daily, pilots and ATCOs must manage crowded airspace where precision and brevity in English communication are critical. Miscommunication on this route could lead to delays, near-misses, or even accidents.

2. Cairo to Jeddah: 5.47 Million Seats

This route connects two culturally distinct regions with varying accents and communication styles. Cabin crew and ground staff must frequently assist passengers navigating the complexities of international travel. For pilots, challenges can arise in understanding air traffic controllers with strong regional accents. Proficiency in English helps bridge these gaps and ensures smooth operations.

3. Seoul to Tokyo Narita: 5.4 Million Seats

Japan and South Korea are both nations with high aviation standards, yet pilots and controllers often rely on English as a second language. Misunderstandings can arise when switching between routine radio phraseology and plain English during non-standard situations like diversions or emergencies.

Why English Proficiency Matters For The Aviation Sector

Pilots

• Busy Airspace: Routes like Bangkok to Singapore and Hong Kong to Taipei are often congested. Pilots must process fast-paced instructions from ATCOs in English. Even a slight misinterpretation, such as confusing “cleared for takeoff” with “line up and wait,” could cause accidents.
• Emergency Situations: In non-routine scenarios, pilots must use plain English to explain problems to ATCOs and coordinate responses. For example, a technical issue mid-flight requires clear articulation to avoid miscommunication.

Air Traffic Control Officers (ATCOs)

• Accent Variability: As air traffic increases, ATCOs handle pilots from diverse linguistic backgrounds. Mispronunciations or unfamiliar accents can create confusion. For instance, in crowded airspace like Singapore Changi or Dubai, controllers must issue precise, easily understood instructions to avoid conflicts.

Cabin Crew

• Passenger Communication: With leisure travel dominating many routes, cabin crew often deal with passengers who may not speak English fluently. Explaining safety instructions or addressing concerns requires clarity and confidence in English.
• Handling Emergencies: In crises, crew members must relay accurate information to passengers and coordinate with the flight deck in English, ensuring safety and calm.

Engineers

• Technical Documentation: Aviation engineers work with manuals, maintenance records, and technical documents written in English. Misinterpreting even a single instruction could lead to catastrophic failure.
• Global Collaboration: Engineers frequently collaborate with colleagues from other countries. Proficiency in technical English facilitates smooth communication during inspections, repairs, and upgrades.

Communication Challenges in a Multicultural Industry

The diversity of passengers and crew on routes such as Dubai to Riyadh or Kuala Lumpur to Singapore underscores the multicultural nature of aviation. However, this diversity comes with challenges:

• Language Barriers: Non-native speakers may struggle with pronunciation or grammar, leading to delays or errors.
• Cultural Nuances: For cabin crew, interpreting a passenger’s needs correctly is crucial, especially when English is the common but non-native language for both parties.
• Time Sensitivity: Pilots and controllers must exchange critical information quickly and clearly, especially during high-pressure situations in congested airspace.

The Need for Better English Proficiency

As travel rebounds, the aviation industry faces increasing demand for skilled professionals who can navigate these challenges. Improving English proficiency offers several key benefits:

1. Enhanced Safety: Clear communication reduces the likelihood of accidents caused by misunderstandings.
2. Operational Efficiency: Strong English skills minimize delays and miscommunication during routine and emergency operations.
3. Global Employability: Aviation professionals with advanced English skills are more competitive in the international job market.

The data from OAG’s report paints a clear picture: the skies are busier than ever, and effective communication is critical. For pilots, ATCOs, engineers, and cabin crew, improving English proficiency isn’t just about career advancement—it’s about ensuring the safety and satisfaction of everyone onboard.
