who is she going to call? the cops or the airline? they knew she was there and wouldnt let her off.
I'm not sure if the cleaning crew intentionally locked her in or what, I heard none of that on the morning drive. If they did, you dial 911 and say you've been kidnapped, they can find you cell phone. If not, still 911, I'm locked inside an airplane, can you tell where I am? etc
I did hear she was detained and questioned after they found her, and rightly so. She was in a secured area where she should not be, and is definitely a security risk. The questioning would eventually lead to the flight attendant's failure to properly inspect the plane, but they are correct to question her.
