Frequently Asked Questions
If a plane icon is moving on the map, yes. That's ADS-B, the aircraft's own GPS position broadcast, updated every few seconds. No icon means the flight isn't airborne at the moment: either before pushback, already landed, or a day it doesn't operate.
Scheduled equipment is the 32B. The live tracker shows the actual tail and registration when NK 268 is airborne. Carriers swap aircraft often enough that you'll sometimes see a different airframe than the scheduled type.
Thu Fri Sat. 3 days a week. On days outside that pattern this page will show the schedule but no live aircraft.
Scheduled 2h 32m gate to gate from IAH to MIA. Actual air time varies with winds and ATC routing. Tailwinds can shave 15 to 20 minutes on long segments.
GPS-accurate via ADS-B. Typically within 30 meters horizontally, updated every 5 to 10 seconds. If the broadcast drops over oceans or mountainous terrain, the map holds the last-known position and the label changes to reflect the signal gap.
