5 WAYS TO HANDLE PASSENGERS

1. Get down to their level: Literally, get down on one knee in the aisle. This position is less threatening to passengers
2. Listen: Most passengers just want to be heard. That's it.
3. Keep calm: Do not raise your voice. Stay in control
4. Just the facts: Ask what the problem is and then have the passenger suggest a solution. Keep emotions at bay.
5. Excuse yourself: A new face is new energy. If you're not getting anywhere with a difficult passenger, remove yourself from the situation and ask a coworker to step in. Even though a coworker may tell a passenger the exact same thing you did, they could get a completely different response.
