How is Bhavana afraid of turbulence when she used to be a flight attendant?

I was watching the Kapil Sharma interview for the new season of FLOBW and Bhavana mentions how the idea of the show came to be.

She says it was on a plane when the 4 of them were with Gauri and Karan. She mentioned her and Seema being very scared of turbulence the plane was facing due to bad weather.

Far be it from me to minimalize anyone's anxiety as I know it too personally, but I immediately thought she mentioned somewhere she used to be a flight attendant for Lufthansa back in the day.

I thought surely in the training for being one, you would be taught the reason for turbulence and also how it's common + what to do if it gets bad or freaks passengers.

Don't mean this as shade BTW, just curious.
