Flight Attendants

We rode to the airport in a shuttle with flight crews heading in for their flights.  I found out that while flight crews get a per diem of about $1.90 per hour while they are on duty, they only get salary pay for the flight. So while they are boarding us and getting us situated, they are making less than $2.00/hr.  Of course, there are many other benefits that offset this.  I just had no clue that they did not get regular salary for all hours they work for a flight.
