The FAA has a plan to reduce delays at New York airports this summer — here's what it means for trav

A change to a longstanding Federal Aviation Administration policy may help clear up congestion in the skies over New York City this summer. It will mitigate delays and help airlines better handle thunderstorms and mechanical issues. However, that might come at the expense of a greater flight choice.


The FAA said this week that it would allow airlines to reduce the number of flights they operate from certain "slot-controlled" airports over the summer without permanently surrendering the valuable takeoff and landing slots. The agency cited ongoing shortages of air traffic controllers, which contributed to delays throughout last summer.

How do airport 'slots' work?

"Slots" are essentially "rights" for an airline to operate at certain high-volume airports. Each slot an airline possesses gives it the right to operate one takeoff or landing. A "slot pair" refers to one arrival and one departure slot. The slot system regulates air traffic flow and prevents dangerous overcrowding at airports. It also prevents anti-competitive entrenchment by carriers.


In the U.S., there are three slot-controlled airports: John F. Kennedy International Airport (JFK), LaGuardia Airport (LGA) and Ronald Reagan Washington National Airport (DCA).


A fourth — Newark Liberty International Airport (EWR) — is considered "schedule controlled" instead. This is a similar system with several minor differences. Unless an airport builds a new runway or otherwise finds a way to increase capacity — further optimizing air traffic control patterns, for instance — the number of slots is finite, and all slots are governed by the FAA.


To prevent airlines from hoarding slots that they don't actually plan to use in order to shoulder out the competition, the FAA enforces a "use it or lose it" rule. Airlines must use each slot at least 80% of the time. Otherwise, the FAA can revoke the slot and give it to another airline.


Voluntary slot returns to combat air traffic control short-staffing


Because of the 80% rule, airlines typically make full use of their slots, occasionally leasing them to other airlines if they can't find a valuable use for them. During slow periods or market changes, airlines have been known to operate unprofitable or unnecessary flights just to avoid losing slots that they expect to need at a later point. This practice is sometimes referred to as "squatting" on slots.


For instance, an airline might run 16 daily flights between a pair of cities like New York and Washington, even though there may only be enough demand to fill 10 flights per day.

The FAA said that it expects airlines to operate roughly 7% more flights to and from New York this summer compared to last year.


Meanwhile, the New York-area air traffic control facility is only staffed at 54% of its ideal level. (Nationally, federal air traffic control centers average roughly 81% of optimal staffing levels, the agency said.) The agency plans to reassign control of the busy airspace around Newark to a control facility in Philadelphia to reduce the workload on the overtaxed New York facility. Still, that shift will not be complete until after the summer.


The combination of more flights and an overtaxed air traffic control center is projected to increase delays by 45%. This would have cascading ripple effects through the entire country's airspace.


To avoid that, the agency said it would give airlines the flexibility to consolidate flight frequencies — which could involve using larger planes for some of the flights — without worrying about losing slots.


Under the plan, airlines could voluntarily shelve up to 10% of their slots from May 15 through Sept. 15, the FAA said. The agency set an April 30 deadline for airlines to choose whether to take advantage of the program.


DCA is included in the program because airlines will likely choose to consolidate flights between New York-area airports and Washington, the FAA said.

How will the slot waiver affect summer travel?

Ideally, if the major airlines can consolidate enough flights and frequencies to maximize the FAA's waiver, the airspace above New York will be less congested this summer. Both airlines and air traffic controllers will have an easier time getting things back on track after unavoidable disruptions like thunderstorms.


However, it could potentially mean that airlines cut frequencies or entire routes that travelers have come to rely on.


Both Delta Air Lines and United Airlines said they would try to return 10% of their slots for the summer while consolidating operations. The airlines said they would upgauge flights to larger aircraft as much as possible and proactively work to accommodate any customers affected by the changes. They also said that, to whatever extent possible, they would use their freed-up DCA slots to fly to destinations other than New York for the summer.


"We are prepared to do our part," Delta chief of operations John Laughter wrote to the FAA in a March 21 letter.


In a letter dated March 22, American Airlines wrote that it was still assessing whether or not to seek the waiver. The letter said the carrier recognized that scaling back its New York operations would "improve airspace conditions and the customer experience in the broader New York region, which has nationwide benefits."


But it's hard to predict which specific scheduled flights will be affected, according to Henry Harteveldt, a travel and airline industry analyst and founder of Atmosphere Research.


"I think the airlines will look to cut flights where they have a reasonable level of frequency and where perhaps cutting one or two flights may not affect their competitiveness and would also not inconvenience passengers too much," Harteveldt said.


Additionally, Harteveldt said that airlines would likely cut routes that have typically performed poorly.


"Airlines have already shown that they're willing to drop certain markets altogether because of high operating costs," he said. "But these are flights to destinations where the profitability performance, or the contribution to airlines' overall traffic and system revenue, is marginal."

The potential good news for travelers living in or flying to smaller markets in the U.S. is that carriers won't likely want to eliminate service as part of the waiver, at least to the extent possible, Harteveldt said.


"I think the airlines are going to try to find the right balance here," he said. "And if you're running seven or eight or more flights a day from one of these airports to another destination, maybe dropping some of those flights is better than dropping flights to a regional destination where you may be their only air service, or where there may be other factors to consider."


With airlines' proposals to the FAA due April 30, it will likely be at least a few weeks before changes are reflected in the airlines' published schedules. TPG frequently reports on airline schedule changes, so check back in the coming weeks as the slot waivers are finalized.
