What change to the schedule was that? How many hours of flights did they change?

And I assume that if a flight is late it can still land or depart if the scheduled arrival or departure was not in this 0000-0500 window.

Do you have a link to the source article? Frankly, I'm a bit skeptical that such an accomodation was made for one lady. I'm not and would never doubt your veracity. I would like to examine the source of this story.

Maybe they accomodated her with an empty promise just to shut her up?
