Why Airlines Are Moving Beyond SMS for Passenger Communication

Airlines across India and globally are beginning to rethink their reliance on SMS as the primary channel for passenger communication. For years, SMS has served as the backbone of airline messaging—used for booking confirmations, check-in reminders, boarding alerts and disruption notifications.

However, as passenger expectations evolve and digital communication channels expand, airlines are seeing declining return on investment (ROI) from SMS-based communication systems.

Today’s passengers expect real-time, interactive and personalized communication, forcing airlines to adopt automated passenger communication platforms that go beyond simple text alerts.

Why SMS Became the Default Airline Communication Channel

SMS became the default channel for airline passenger communication primarily due to its universal reach and reliability.

Every mobile phone can receive SMS messages without requiring internet connectivity. For airlines operating across multiple geographies, this ensured that important flight information could be delivered quickly and reliably.

Historically, SMS has delivered strong performance metrics:

• – SMS open rates close to 98%
  
• – Extremely high delivery rates
  
• – Instant delivery for time-sensitive notifications
  
• – No dependency on mobile apps or data connections

For airline operations teams managing flight delays or gate changes, SMS was the fastest way to reach passengers.

However, while delivery and open rates remain high, airlines are beginning to see declining engagement, scalability and cost efficiency.

The Challenges of SMS in Modern Airline Communication

1. High Messaging Costs at Scale

Airlines send millions of passenger notifications each month. With SMS priced per message segment (typically 160 characters), longer notifications or multilingual alerts significantly increase messaging costs.

For global airlines sending international messages, cross-border carrier charges further increase expenses.

During large operational disruptions or IRROPs (Irregular Operations), airlines may send multiple notifications per passenger—rapidly escalating communication costs.

2. Limited Rich Communication Capabilities

SMS is fundamentally limited to basic text communication.

Modern airline communication strategies require capabilities such as:

• – Digital boarding passes
  
• – Interactive check-in flows
  
• – Real-time flight status updates
  
• – Seat upgrades and ancillary offers
  
• – Duty-free catalogues
  
• – Customer service conversations

These experiences require rich media messaging and interactive communication, which SMS cannot support effectively.

3. Minimal Analytics and Engagement Tracking

One of the biggest limitations of SMS for airline communication is the lack of engagement insights.

Airlines cannot easily track:

• – Whether passengers clicked a link
  
• – Whether a boarding pass was downloaded
  
• – Whether ancillary offers were viewed or purchased

Without these analytics, airlines struggle to measure campaign performance or optimize communication strategies.

Modern airline passenger engagement platforms require deeper insights into passenger behavior to improve both customer experience and revenue opportunities.

Changing Passenger Communication Preferences

Passenger communication habits have evolved dramatically over the last decade.

Messaging apps now dominate daily communication worldwide.

Passengers increasingly prefer communicating with businesses through messaging platforms rather than traditional SMS.

In India especially, messaging platforms have become the primary communication medium for both personal and business interactions.

Why Airlines Are Turning to WhatsApp

Messaging platforms like WhatsApp are rapidly becoming the preferred channel for airline passenger engagement and automated notifications.

WhatsApp offers several advantages over SMS:

Higher Engagement

• – Open rates as high as 98%
• – Faster response times
• – Higher message interaction rates

Rich Communication Features

Airlines can deliver:

• – Boarding passes
• – Flight updates
• – Interactive menus
• – Check-in reminders
• – Customer support conversations

Two-Way Passenger Communication

Unlike SMS, WhatsApp enables passengers to respond, ask questions and interact directly with airlines, improving overall customer experience.

The Rise of Omnichannel Passenger Communication

While WhatsApp is rapidly growing, the future of airline communication lies in omnichannel passenger engagement platforms.

Different passengers prefer different communication channels depending on geography and demographics.

Modern airline communication strategies therefore combine multiple channels including:

RCS (Rich Communication Services): The next generation of SMS with interactive capabilities.

Email: Still critical for itineraries, receipts and long-form communication.

Viber and Telegram: Popular messaging platforms in Eastern Europe and parts of Asia.

WeChat: Essential for airlines serving Chinese travelers.

Mobile App Push Notifications: Effective for frequent flyers who actively use airline apps.

Airlines increasingly need flexible passenger communication platforms that integrate across all these channels.

The Future of Airline Passenger Communication

As airline digital transformation accelerates, communication systems must evolve beyond static notification channels.

Modern airline communication platforms must support:

• – Automated passenger messaging
• – Real-time operational notifications
• – Disruption optimization communication
• – Personalized passenger engagement
• – Omnichannel communication delivery

This shift is driving the adoption of intelligent passenger communication platforms across the aviation industry.

How 22North Enables Intelligent Airline Communication

22North by Phonon is designed to power the next generation of automated passenger communication for airlines and airports.

Unlike traditional airline messaging systems, 22North provides a fully integrated omnichannel passenger communication platform capable of delivering notifications across SMS, WhatsApp, RCS, email and other messaging channels.

Airlines can orchestrate the entire passenger communication lifecycle—from booking confirmations and check-in reminders to disruption notifications and post-flight engagement—from a single intelligent platform.

22North integrates seamlessly with airline operational systems including reservation platforms, passenger service systems and airport operations technology. This allows airlines to trigger real-time communication based on operational events such as flight delays, gate changes, loyalty tier upgrades or ancillary offers.

By delivering contextual, personalized and automated communication across passenger journeys, airlines can significantly improve customer experience outcomes.

Passengers receive timely, relevant information through their preferred communication channels, while airlines gain complete visibility into engagement metrics and campaign performance.

The result is stronger passenger engagement, higher customer satisfaction scores in CSAT surveys and improved loyalty across frequent flyer programs.

In an industry where operational complexity and passenger expectations continue to grow, intelligent communication platforms like 22North are becoming essential infrastructure for modern airlines.
