It's pretty dense...

Not dense, but confusing.
For starters, the start is unclear. You're commenting on something the DOT has done, but instead of telling us just what that is, you link to a 115 page document.
Then comes the background, but it's hard to hold the reader's interest in this when they still don't know what it's the background for.
"...if they changed your flight more than 2 hours" Does this mean:
a. if your flight time was 2 hours longer than scheduled
b. if they changed your scheduled flight more than 2 hours before departure
c. if your departure time was more than 2 hours later than originally scheduled
I think it's c, but not really sure.
