The Airbus A320neo has just left the gate in Zurich. Sitting by the window is Milow, heading off for a long weekend by the sea. While the aircraft is still taxiing towards the runway, he picks up his smartphone and sends his sister a short message: “We're off.”

A little later, the Alps pass far below the aircraft. Snow-covered peaks, rugged cliffs and green valleys create a view Milow does not want to keep to herself. He snaps a picture and taps “send”.

For Milow, it takes only a moment.

But before the photo appears on her sister's screen, it travels a remarkable route. It passes through the aircraft, is sent hundreds of kilometres into space and finds its way back to Earth via satellites and ground stations.

Milow notices none of this. For him, the connection simply works. Behind the small Wi-Fi symbol lies a network of antennas, satellites and communication systems that will help our guests stay connected more quickly and reliably while travelling.

The journey begins in the cabin

Before Milow's message can take off, it first has to find its way through the aircraft. His smartphone is connected to Lufthansa Group Wi-Fi powered by Starlink and sends the data to one of the wireless access points located throughout the cabin.

These devices work much like a Wi-Fi router at home. Because an aircraft cabin is far larger than a living room, several access points distribute the signal throughout the aircraft, helping guests stay connected regardless of where they are seated.

From there, the data continues its journey through the aircraft. Its destination is only a few metres away, yet already outside the cabin: two flat antennas mounted on top of the fuselage.

The gateway to space

The antennas connect the aircraft to the satellite network. They are designed to blend seamlessly into the fuselage while maintaining the aircraft's aerodynamic profile.

As soon as the data reaches the antennas, it is transmitted to a Starlink satellite. Unlike traditional television satellites, these satellites do not remain fixed above the same point on Earth. Instead, they move continuously around the planet together with thousands of other satellites in low Earth orbit.

While the aircraft travels towards its destination at around 900 kilometres per hour, the satellites race around the Earth at several thousand kilometres per hour. Whenever one satellite moves out of range, the next seamlessly takes over. Passengers never notice these handovers.

Milow's message is now truly on its journey. From the aircraft antenna it travels to a satellite. From there it is transmitted either directly, or via other satellites, to a ground station connected to the internet. The reply follows the same route back and appears on Milow's screen moments later.

Why it is faster

Satellite internet on aircraft is not new. The difference lies mainly in the distance.

Some previous systems use geostationary satellites positioned around 36,000 kilometres above the Earth. From there, they appear to remain over the same point on the planet. For every signal, however, that means a very long journey.

Starlink satellites orbit much closer to Earth, at approximately 330 to 550 kilometres. As a result, data has a much shorter distance to travel. Websites load faster, photos are sent more quickly and access to cloud applications or corporate networks becomes more responsive.

Put simply: the data no longer has to take a long detour. It reaches its destination more directly.

Before the first message can travel

Long before Milow sent his photo, the work had already begun.

In the maintenance hangar, the SWISS Maintenance team prepared the Airbus A320neo for the new system. They installed the two antennas on the fuselage. Inside the aircraft, they added power supply units and connected the system to the cabin Wi-Fi network through dedicated data lines.

What can be described in a few sentences requires considerable precision. Teams install mounting structures, run cables and connect the various components. Every modification must be approved for the specific aircraft type. This often means working in areas passengers never see, such as behind cabin panels or inside the cockpit.

Today, the work on the first SWISS Airbus A320neo has been completed. Before the first passengers could use the new Wi-Fi service, every connection was carefully tested. Only after all checks were successfully completed was the system approved for operation.

 

Staying connected whenever you want

For Milow, the difference is easy to notice. Shortly after boarding, she is online and remains connected until arrival. The message before departure, the photo above the clouds and the email sent shortly before landing all reach their destination within seconds.

What sounds technically complex feels completely natural to the passenger: the connection is there when it is needed.

Video calls, internet telephony and active live streaming, however, remain unavailable on board. Even with new possibilities, the cabin should continue to be a pleasant and considerate environment for everyone travelling.

Back at the seat

Inside the cabin, none of this is visible.

No satellites. No ground stations. No data cables.

Only the Wi-Fi symbol on Millow's smartphone.

His photo has long since arrived. A moment later, his sister's reply appears:

"What a view!"

That message also travels hundreds of kilometres into space, switches satellites, reaches the antennas on the aircraft and finds its way back to Mia's seat via the onboard Wi-Fi network.

For Milow, however, it all comes down to one small moment.

His phone vibrates.

He smiles.

The connection is there.
