Plot hole: Towards the beginning of the movie Dorothy first "meets" Jerry by eavesdropping on his conversation with a woman in the airplane. But Jerry is located in First Class whereas Dorothy is in Coach. Going by her seat location it seems like she's sitting at least 10 rows from Jerry, plus the area that divides Coach from First Class between them. And Jerry is speaking in a soft voice. Add to that the drone that an airplane makes (even if not airborne) and it's highly unlikely that she would have been able to hear him, even if he was the only person talking in the plane (also unlikely).
