Prepare for the Gogo legacy ATG network shutdown. Learn how aircraft operators can upgrade to AVANCE L3/L5, avoid downtime, and ensure future-ready inflight connectivity.
As an aviation professional who’s worked alongside operators navigating avionics upgrades for years, I can say with confidence: the Gogo network migration is one of the most impactful shifts in inflight connectivity we’ve seen in a decade. With the impending sunset of Gogo’s legacy ATG network, aircraft operators across the U.S. are facing a critical decision point — adapt with AVANCE or risk being left in the digital dark.
Let’s break down what’s changing, why it matters, and how to stay ahead of the curve.
Gogo Business Aviation’s legacy Air-to-Ground (ATG) network, once the backbone of inflight connectivity for thousands of business jets, is being phased out due to aging infrastructure and the demand for higher-speed, lower-latency data. With evolving passenger expectations and increasing bandwidth needs from both pilots and passengers, the 3G-based legacy system simply can’t keep up.
Upgrading to AVANCE systems allows for more modern, scalable connectivity — and paves the way for next-gen services like Gogo 5G.
The legacy ATG network is “scheduled” to go offline by the end of 2025. After this date, aircraft still equipped with legacy-only systems will experience full loss of inflight connectivity. This includes loss of cabin Wi-Fi, SMS, VOIP, and any connected cockpit applications relying on that network.
Operators who delay their upgrade risk not only service loss but also longer installation lead times as demand surges closer to the cutoff date.
Gogo AVANCE is a modular platform designed to deliver high-performance inflight Wi-Fi, entertainment, and connected services. AVANCE L3 is built for light to mid-size jets with lower data demands, while AVANCE L5 serves mid-to-large cabin aircraft and high-usage operations.
Both units offer secure, reliable internet via Gogo’s enhanced ATG network — and AVANCE L5 is 5G-ready, allowing a seamless transition to Gogo 5G service upon launch.
Enhanced Wi-Fi Speed and Bandwidth
Passengers will experience faster browsing, smoother streaming, and more reliable VPN or conference calling — even with multiple devices onboard.
More Reliable Coverage and Passenger Experience
AVANCE systems dynamically manage onboard bandwidth and prioritize business-critical applications, giving operators more control over connectivity while improving passenger satisfaction.
Compatibility with Gogo 5G
AVANCE L5 is fully compatible with Gogo 5G hardware. Upgrading now future-proofs your aircraft and avoids another costly retrofit in just a few years.
After the shutdown, any aircraft still using legacy-only equipment will go completely offline inflight. This poses serious risks for charter operations, business travelers, and flight crews relying on connected tools for scheduling, dispatch, or flight optimization.
Gogo is currently offering aggressive upgrade incentives, including hardware trade-in credits, subscription discounts, and deferred billing options for operators upgrading to AVANCE before the migration deadline.
Sky Aircraft Maintenance is bundling installation packages with 10–15% discounts on labor and additional services from scheduled maintenance that is done at the same time as your Gogo upgrade.
Forward-thinking operators are combining AVANCE installs with scheduled maintenance checks (Phase, A/B/C checks, etc.) to minimize downtime.
With installation lead times already stretching, booking now ensures hangar space and parts availability.
Determine if your aircraft is still operating on a legacy ATG-only system.Â
If so, confirm whether your system is AVANCE-compatible or will require a full retrofit.
AVANCE L3: Ideal for aircraft with fewer passengers or shorter mission profiles.
AVANCE L5: Recommended for larger cabins, higher passenger volume, or frequent coast-to-coast operations.
Slots are limited, and lead times can exceed 12 weeks. Contact your preferred FAA-certified installer or MRO now to reserve a window that aligns with your maintenance calendar.
As we near the end-of-life date, availability will tighten. Acting now gives you leverage in scheduling and ensures you’re not grounded by delays.
Sky Aircraft Maintenance is bundling installation packages with 10–15% discounts on labor and additional services from scheduled maintenance that is done at the same time as your Gogo upgrade.
Gogo’s financial incentives — including hardware discounts and subscription rebates — and 100% bonus depreciation — are time-limited. Waiting could mean paying significantly more later.
Upgrading to AVANCE L5 doesn’t just keep your aircraft connected — it positions you for seamless Gogo 5G integration, better cabin experiences, and stronger resale value.
We work with FAA-certified MROs and avionics specialists who have immediate availability for Gogo installations.Â
Whether you’re upgrading one jet or an entire fleet, our team can guide you through the process from equipment selection to final certification.
