Usable wifi, video included. Next-gen is inside this count. It is not a second, matching number.
What Streaming means
Aircraft where video works. 56 aircraft, 100%. That includes the 56 next-gen tails plus 0 with older satellite wifi that still streams. This card shows coverage, not a quality score.
The rest of the fleet
After next-gen and streaming, the leftover is older onboard wifi, no wifi, or no published system. Older satellite wifi that still streams is already in the Streaming card, not a vendor tile here.
Older onboard wifi Cabin systems that are not the streaming bucket.
0
No wifi Published as unequipped.
