Across all seasons, actual EWR arrival rates were less than the planned 40 landings per hour in 31.4% of hours. Let’s tack on the other half of the year, though we’ll look back to April-October of 2018, when runway rehabilitations caused less distortion. How does that compare to realized arrival capacity? Since Octo7, arrival rates have been less than 40 during 29.6% of hours-and that’s during the generally more benign, less convective half of the year. On account of this intractability, we’ll halve (and round up) the 79 operations per hour to get a 40 landings per hour cap. What is this theoretical capacity Scott mentions? And EWR has again assumed its spot as laggard, giving up more than a percentage point of EDCT incidence to LGA and 8.7 percentage points to JFK. From Octoto April, 26, 2022, 9.7% of arrivals to EWR were assigned an EDCT, up from less than 1% during the same period the year prior. With flight schedules trending towards more normal levels-and the demand for airports’ runways that they represent-delays have responded in kind. Resultantly, frequencies at EWR, JFK and LGA, which were languishing at 69% of 2019 levels in October 2021, quickly bounced to 93.1% in November. Thereafter, its scope was pared back 6 to waive usage requirements for international operations only. With the onset of COVID, the FAA announced a slot usage waiver on Mathat applied to Level 3 and 2 airports 5 the waiver would be thrice extended, availing relief through October 30, 2021. This pattern would broadly continue through 2019, with 26.8% of EWR arrivals assigned an EDCT 4 -ceding 5.3 percentage points in EDCT incidence to LGA and 19.2 percentage points to JFK. For their part, nearby-and still slotted-New York-LaGuardia (LGA) and JFK were up 5.5 percentage points (to 19%) and down 0.2 percentage points (to 4.8%), respectively. In the following 90 days, 24.8% of arrivals to EWR were assigned an EDCT, nearly doubling from 12.8% during the same period the year prior. The effects of the transition to a Level 2 designation were apparent almost immediately. The 2008 order was allowed to expire on Octopursuant to the April 1 announcement, in which the FAA referenced improved EWR operational metrics while also alluding to planned 2017 runway construction at JFK. The order originally designating EWR as a Level 3 3 took effect in 2008 and pointed to concerns about spillover effects from New York-Kennedy (JFK). The new designation meant that EWR would no longer be slot-coordinated, but schedule facilitated practically, it required that the FAA seek voluntary schedule adjustments from airlines to alleviate delays. On Ap(in what some 2 initially thought was a very uncharacteristic April Fool’s joke), the FAA announced that EWR would transition from a Level 3 to Level 2 airport.
