Has the trend since the advent of air travel been toward more or fewer delays, over total flights? Most anything I can find deals with specific airlines, airports, and aircraft, but I’m just interested in the general trend for US flights.

Thanks, but I found that already and it’s basically unusable for the information I’m looking for.
I was hoping someone knew of a study or source of more broad or summarized statistics.
