For many airlines, WhatsApp has quietly become one of the most important communication channels in their toolkit. Passengers value it because it is instant, familiar, and personal. Airlines value it because it delivers messages quickly, without getting lost among crowded inboxes. 

Today, more than 2.9 billion people around the world use WhatsApp. In countries like India and Brazil, it is not just popular, it is the main way people stay connected. And in Europe, it’s often the first thing people check each morning.

So even though some changes are coming to the way WhatsApp Business messages are charged, airlines should continue to keep WhatsApp at the heart of their communications strategies. With the right approach, it remains one of the most powerful and cost-effective ways to connect with passengers. 

Here’s what is changing, what it means for airlines, and how 15below can help you make the most of it. 

What is changing in WhatsApp pricing?

From 1 July 2025, Meta (WhatsApp’s parent company) introduced a new Business pricing model.

Previously, when a business sent a message that opened a conversation with a customer, it paid one fixed price for a 24-hour window - no matter how many messages were exchanged in that time. From July however, businesses now pay based on the number of individual messages they send.

Meta is also adjusting how conversations are categorised. Going forward, there will now be four types:

• Marketing – messages that promote or sell
• Utility – updates like flight status, gate changes, or booking confirmations
• Authentication – messages used for verification and security
• Service – conversations that are started by a customer

There is good news for airlines - service conversations will still be free for 24 hours after a passenger contacts you, and utility messages sent within that service window will not carry extra costs. This means many of the essential communications airlines send, like urgent disruption updates, can still be delivered without additional charges.

What WhatsApp changes mean for airlines

The shift to per-message pricing brings new considerations, but it is not a reason to reduce your use of WhatsApp.

1. A more efficient approach to messaging

With the new pricing model, every message matters. This encourages airlines to be clearer and more efficient - for example, by combining multiple updates into a single message where it makes sense. If there is both a gate change and a delay, sending one complete update is better than two separate notifications. Passengers will appreciate fewer but more helpful messages - and airlines will be able to manage costs without affecting service.

2. Passenger expectations remain high

Passengers are not concerned with pricing models. They simply expect fast, useful updates through the channels they know and trust. WhatsApp continues to be one of the most effective ways to reach passengers. In many regions, passengers are much more likely to see and act on a WhatsApp message than an email or SMS.

Choosing not to use WhatsApp could damage trust and create frustration, especially during disruption. The airlines that continue to communicate clearly and personally on WhatsApp will be the ones passengers remember for the right reasons.

3. Building a flexible communication strategy

WhatsApp should not be used for everything. It works best when it forms part of a broader, multi-channel communication approach. Some types of updates might be better sent by SMS, email, or app push notification, depending on urgency, message length, and passenger preferences.

Creating a strong communications system means making sure each message is sent using the best method available - ensuring reliability, passenger satisfaction, and sensible cost control.

Why WhatsApp remains essential for airlines

Even with the pricing updates, WhatsApp continues to offer something few other channels can match: fast, direct communication that feels personal and natural. It is trusted. It is familiar. It allows airlines to speak to passengers in the same place they already communicate with family, friends, and businesses they rely on.

The data shows just how important WhatsApp has become:

• India: India has around 535.8 million monthly active WhatsApp users, making it the largest WhatsApp market in the world.
• Brazil: Around 93% of internet users in Brazil use WhatsApp.
• Europe: In Spain, WhatsApp usage reaches 92% among the general population, with Italy and Germany also seeing rates above 80%.

In many parts of the world, if you are not communicating via WhatsApp, you’re missing out on a significant opportunity to add value for your passengers.
