Gate Cameras Shave Four Minutes Off Every Alaska Airlines Turn
Quick Summary
Alaska Airlines runs computer vision on its existing gate cameras in Seattle to time-stamp every step of an aircraft turnaround and warn the ramp crew when a task is running late. Turn times fell 12%, close to four minutes per departure.
The Use Case
A late catering truck or a missing bag cart delays one departure, and that delay cascades through the day's schedule. Crews coordinated by radio and eyeballing. Assaia's software watches the gate cameras already in place, recognizes about 32 kinds of equipment and events (belt loader arrives, door opens, cones removed, pushback), stamps each milestone, compares it to the plan and predicts when the aircraft will actually be ready. If a step is behind, the ramp team gets an alert while there is still time to fix it. At roughly $100 per minute of turn time, four minutes a departure adds up quickly.
Real Example
- The aircraft arrives and the camera logs chocks-on at 10:02
- Bags are off by 10:09, but the catering truck has not appeared by 10:15, five minutes late
- The system alerts the turn coordinator and updates the predicted ready time
- Catering is redirected from a nearby gate and arrives at 10:19
- Every milestone through pushback is stamped without anyone typing
- The day's turns are reviewed on a dashboard to find which tasks slip most often
Why It Matters
- Seattle turn times down 12%, nearly 4 minutes saved per departure
- Milestones are captured automatically, replacing radio calls and manual logs
- Other users report a 25% drop in last-minute gate changes (Schiphol) and 75% fewer flights waiting to dock (Spirit)
