How airlines react to this decision may lead to reduced delays at airports like New York La Guardia or Chicago O'Hare.
A major contributing factor to airport delays is airport and airspace congestion. Airlines contribute to this problem by having too many flights operating at congested airports. For the stated case of remaining competitive, airlines will operate numerous flights with smaller aircraft between certain paired cities.
Many times these routes (New York, Boston, Chicago) are flown by 50-90 seat aircraft that require most of the same airport and airspace considerations.
Even passengers inconvenienced by scheduling changes will benefit if over all airport congestion and delays are reduced.
By imposing higher landing fees at certain times of the day airports hope to influence airline scheduling policies. Although I am not fond of government intervention in business sometimes it becomes necessary.
I agree with the court's decision in the case of Department Of Transportation versus The Air Transport Association (ATA). The court stated, “As the airspace is used ever more intensively, it is unsurprising that the department would update its approach to landing fees in an effort to relieve airport congestion”.
