This is a little random, but I've noticed recently (at least my last 6 flights) that the pre-takeoff announcement to the flight attendents no longer includes "verify straps" (i.e., "flight attendants: cross check, verify straps, standby for all call"). It seems like CO still uses the straps across the window to indicate that the slides are armed, but no longer reminds the FAs to double check them. Is there some reason for the change? Just curious...
