How to Get Faster, Steadier Internet on a Plane
Speedify bonds in-flight Wi-Fi with other available internet connections (including 4G/5G cellular when available during taxiing, approach, and low-altitude segments) to give airline passengers and crew faster upload and download speeds and more reliable connectivity. When the in-flight Wi-Fi connection degrades or drops, Speedify automatically manages traffic across available connections without interrupting active sessions.
This article covers how Speedify works in aviation environments, how airlines and passengers can benefit, and what deployment options are available.
Why In-Flight Internet Is a Persistent Problem
In-flight internet connectivity has improved significantly over the past decade, but it remains one of the most constrained and unreliable internet environments passengers encounter. The root causes are structural:
- Aircraft in-flight Wi-Fi systems share a single satellite or air-to-ground internet connection across all passengers on board. Upload and download speeds available per user drop sharply as more passengers connect and actively use the network.
- Satellite handoffs during flight cause brief but disruptive outages that reset active sessions: video calls disconnect, file transfers abort, and VPN tunnels drop.
- Coverage gaps over certain oceanic and polar routes leave aircraft with no available internet connection for portions of the flight.
- In-flight Wi-Fi systems vary widely by aircraft type, airline, and service provider. A passenger traveling on multiple airlines in a week may encounter dramatically different connectivity quality on each flight.
For airline crew and corporate travelers who need to stay productive and connected during flights, these limitations have direct operational costs. For airlines deploying connected operational systems for cabin crew and flight operations, unreliable in-flight internet is a reliability risk.
How Speedify Improves In-Flight Internet
Speedify’s channel bonding technology bonds the in-flight Wi-Fi connection with any other available internet connections on the passenger’s device.
During ground operations (taxiing before takeoff and after landing), a device with an active cellular connection can bond the 4G/5G cellular connection with the in-flight Wi-Fi for faster combined upload and download speeds.
Once airborne and beyond cellular range, Speedify routes all traffic through the in-flight Wi-Fi connection and manages the connection actively to reduce the impact of packet loss and congestion.
Speedify’s Redundant Mode is particularly useful for in-flight VoIP calls and video conferences during the cellular-available ground segments: Speedify sends each data packet over both the in-flight Wi-Fi and the cellular connection simultaneously, so the session continues without interruption as the aircraft moves between cellular coverage and in-flight Wi-Fi.
For all in-flight internet use, Speedify’s VPN encryption protects all traffic from other passengers on the shared in-flight Wi-Fi network, a relevant security consideration given that in-flight Wi-Fi is a shared public network.
Speedify and Dedicated Bonding Hardware, Compared for In-Flight Internet
| Feature | Dedicated bonding routers (Peplink, Teltonika and similar appliances) | Speedify |
|---|---|---|
| What you buy | A bonding router appliance for every site or vehicle | A software subscription per user, running on devices you already operate |
| Typical entry cost | From roughly $500 for an entry LTE router to several thousand for a multi-SIM unit, plus a vendor cloud subscription | $89.99 a year per user, billed yearly |
| Internet connections bonded | Ethernet, Wi-Fi and cellular, limited by how many SIM slots the model has | Ethernet, Wi-Fi, 4G/5G cellular and Starlink, up to 31 connections |
| Maximum bonded throughput | Around 200 Mbps through the vendor’s bonding cloud on common models | 300 Mbps on shared servers, up to 1 Gbps on a Dedicated Server |
| Static IP and port forwarding | A vendor cloud add-on | A Dedicated Server or Self-Hosted Server add-on, from $75 a month |
| Central management | The vendor’s own dashboard | The Speedify Teams dashboard, with per-device analytics and a REST API |
| Moving between sites or vehicles | Ship or reinstall the appliance | Sign in on another device |
| If you do want hardware | Required | Optional: a Router License on a compatible OpenWrt router, or the Miri X510 |
In-Flight Internet Setups with Speedify
- In-flight Wi-Fi plus 4G/5G cellular (ground and low-altitude segments). Connect your device to both the in-flight Wi-Fi and your device’s 4G/5G cellular connection during taxiing and in the period after takeoff before cellular signal is lost. Speedify bonds both connections for maximum combined upload and download speeds during this window and transitions smoothly to in-flight Wi-Fi only as cellular coverage drops off.
- In-flight Wi-Fi with Speedify encryption and optimization. On a device with only in-flight Wi-Fi available, Speedify still provides value: VPN encryption protects all traffic on the shared passenger network, and Speedify’s connection management reduces the impact of packet loss and congestion on active sessions.
- Multi-device bonding for cabin crew and operational systems. Airlines deploying connected devices for cabin crew operations can use Speedify for Routers on an onboard router to bond the aircraft’s in-flight internet connection with any available cellular connections during ground segments, providing all connected crew devices with a bonded, more reliable internet connection for operational apps.
How to Set Up Speedify for In-Flight Internet
- Install the Speedify app on your laptop, phone, or tablet before your flight. Speedify runs on Windows, macOS, iOS, and Android.
- At the gate or during taxiing, connect to the aircraft’s in-flight Wi-Fi. Your device’s 4G/5G cellular connection will still be active. Open Speedify. Speedify automatically detects both connections and begins bonding them.
- Speedify prioritizes the faster and more reliable connection for each type of traffic. As the aircraft climbs and cellular signal is lost, Speedify routes all traffic through in-flight Wi-Fi automatically. No manual configuration required.
- Speedify’s VPN encryption is active for all traffic throughout the flight, protecting your data on the shared passenger network.
- For business travelers managing multiple devices, set up a Speedify Teams account to deploy Speedify across all devices in your travel fleet and monitor connectivity performance across team members.
Who Benefits From Speedify for In-Flight Internet
- Corporate and business travelers. Executives and business teams who need to stay productive on flights use Speedify to maximize the upload and download speeds available from in-flight Wi-Fi and to keep video calls and VPN sessions running through satellite handoffs and connection fluctuations.
- Airline cabin crew and operational teams. Airlines deploying connected tablet and device programs for cabin crew benefit from Speedify’s ability to bond in-flight internet with cellular during ground operations, providing more reliable connectivity for operational apps during the periods when crew most actively use connected systems.
- Remote workers and digital nomads. Frequent travelers who work while flying need a reliable, encrypted internet connection that works across different in-flight Wi-Fi systems and providers. Speedify provides a consistent connectivity layer regardless of which airline or service provider is being used.
- Aviation maintenance and ground operations teams. Ground-based operations teams accessing cloud systems and communications tools from airport environments with unreliable Wi-Fi can use Speedify to bond airport Wi-Fi with 4G/5G cellular for more reliable connectivity during aircraft turnaround and maintenance operations.
