In-flight connectivity is no longer a luxury; it’s an expectation. By May 2026, Gogo Business Aviation will retire its legacy air-to-ground (ATG) network, which will make connectivity upgrades essential for thousands of aircraft owners operating with older ATG systems.
What is the Gogo LTE Migration?
Gogo is transitioning from its legacy 3G ATG network to a faster, more secure LTE aviation connectivity system. The change will render affect existing equipment such as the ATG 1000, 2000, 4000, and 5000 inoperative once the migration is complete.
Aircraft that have not been upgraded by the May 2026 deadline will lose in-flight Wi-Fi service, impacting both passengers experience and operational efficiency.
Why does the Gogo LTE Migration matter for operators?
Beyond passenger convenience, connectivity plays a key role in modern operations. From real-time communications to maintenance data transfer, reliable Wi-Fi is essential.
Waiting too long to upgrade can lead to:
- Loss of connectivity once the 3G ATG network is shut down
- Reduced aircraft resale value for non-upgraded models
- Longer installation wait-times as demand increases with May 2026 deadline
Upgrade Options
Operators have several upgrade options depending on their use and budget.
- Upgrade to Gogo AVANCE L3 or L5 for LTE capability
- These systems deliver LTE‑level performance, improved bandwidth, and a more robust platform for future connectivity enhancements.
- Transition to the Gogo Galileo HDX
- For operators seeking future‑proof, global, and satellite‑based connectivity, the Galileo HDX network offers high‑speed performance and redundancy beyond traditional ATG systems.

Quick FAQ
What is the Gogo LTE migration?
The Gogo LTE migration is the transition from Gogo’s legacy 3G air-to-ground (ATG) network to a faster, more secure LTE-based connectivity system. Once the migration is complete, older ATG equipment will no longer function.
When is the Gogo LTE migration deadline?
Gogo will retire its legacy 3G ATG network in May 2026. Non-compliant aircraft will lose in-flight connectivity at this time.
Which Gogo ATG systems will stop working after the migration?
Legacy systems including ATG 1000, ATG 2000, ATG 4000, and ATG 5000 will become inoperative once the 3G network is shut down.
What happens if I don’t upgrade my aircraft before May 2026?
Aircraft that are not upgraded will lose in-flight Wi-Fi service, which can impact passenger experience, operational efficiency, and aircraft resale value.
What are the main upgrade options for business aircraft?
Operators can upgrade to Gogo AVANCE L3 or L5 for LTE-based air-to-ground connectivity, or transition to Gogo Galileo HDX for satellite-based, global connectivity and future-proof performance.
When should operators start planning their upgrade?
Now. Early planning helps secure installation slots, manage costs, and align connectivity upgrades with scheduled maintenance to minimize downtime.
