Summary

  • At 30 September 2026, Gogo reported 5,399 air-to-ground aircraft online, down from 6,529 a year earlier. Galileo LEO aircraft online rose from 18 to 297; GEO aircraft online slipped from 1,343 to 1,285.
  • Third-quarter service revenue declined from $190.0 million to $182.7 million. ATG service revenue fell by $15.6 million, while satellite broadband and narrowband service revenue together rose by $8.4 million. The new lines have not yet filled the old line's revenue hole.

The September 10-Q puts two clocks on Gogo's transformation. One counts aircraft still using its air-to-ground service: 5,399 at quarter-end, 1,130 fewer than a year earlier. The other counts Galileo low-Earth-orbit aircraft receiving service in the final month: 297, up 279. Both movements are real. The second is exciting. The first is much larger in absolute size.

That comparison is a pressure gauge, not a fleet subtraction. The filing defines ATG, GEO and Galileo online aircraft by service and timing, and a plane can appear in more than one connectivity population. The public figures do not establish how many unique planes switched, how many were lost, or what an individual Galileo aircraft pays. Treating 279 new LEO aircraft as a direct replacement for 1,130 fewer ATG aircraft would turn separate operating measures into a fictional migration ledger.

The income statement is less forgiving than the product story. Service revenue was $182.7 million in the third quarter, versus $190.0 million a year before. Within that, ATG broadband service revenue dropped from $71.1 million to $55.5 million. Satellite broadband rose from $78.5 million to $83.9 million, and narrowband and other service revenue from $40.4 million to $43.3 million. Those two increases together recovered roughly $8.4 million against an ATG decline of roughly $15.6 million. The SEC-filed results exhibit also shows 94 Gogo 5G aircraft online within the ATG total. The new terrestrial product has entered the count; it has not stopped the total from falling.

Equipment shipments make a useful sales signal and a poor substitute for that service count. Gogo shipped 172 Galileo units to distribution partners in the quarter, compared with 88 a year earlier. Its own definition includes units used for supplemental type certification. A box at a partner is not an aircraft providing recurring service. The company says near-term service revenue will decline as ATG and GEO services fall, before more Galileo and 5G aircraft come online. That forecast describes the uncomfortable middle of the crossing, not its completed outcome.
