Biometric boarding
A number of airlines and airports seem to be running trials (or will be in the next few months) involving face recognition boarding. Clearly this is about drastically reducing or even eliminating the cost of having ground staff at a gate.
Everything says how it will be voluntary... but unless the trials meet huge public resistance, you can be certain those voluntary single route trials will be deployed on all routes and flying will become more difficult for those pax who decline to take part.
Would anyone involved in this be able to say what's planned to happen by 2024 or 2025 ?
