DEN Delays

Every reading taken of DEN since this site started sampling the FAA's feed — what was holding traffic, why, and for how long. 2 of the 5 were ground delay programmes, the kind that costs an airline money. The worst hold recorded was 4h 38m.

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 DEN cannot take them, and is the one that costs an airline money. The reason is quoted as the FAA writes it.
