JFK Delays

Every reading taken of JFK since this site started sampling the FAA's feed — what was holding traffic, why, and for how long. 9 of the 16 were ground delay programmes, the kind that costs an airline money. The worst hold recorded was 6h 29m.

16 readings

Newest first. The FAA keeps none of this, so every row here is a sample that would otherwise be gone.

Source: the FAA's national airspace status feed. A ground delay programme holds aircraft at their origin because JFK cannot take them, and is the one that costs an airline money. The reason is quoted as the FAA writes it.
