Enplaned passengers in Anchorage International Airport (ANC)

About this data

Monthly enplaned passengers, outbound air freight, and departures for

Anchorage and Fairbanks from BTS T-100 Segment data (all carriers, all

service classes). ANC is one of the world's top-five cargo airports —

CY2025: 2.71M enplanements and 2.91M short tons of outbound freight —

and this is the demand-side pair to the FAA OPSNET activity counts.

Known issues & gotchas

• **The old plan pointed at data.transportation.gov — that domain has no

aviation data** (3 non-aviation assets, verified). data.bts.gov is the

home.

• Freight and mail are POUNDS — converted to short tons (÷2000) at

parse; publishing raw pounds is the classic 2000× error.

• All Socrata numeric fields arrive as JSON strings; reporting_month

is a floating timestamp — parse the date part, never timezone-shift.

• The mirror refreshes irregularly (observed ~6.5 weeks stale) on

top of T-100's ~3-month production lag — freshness expectations are

deliberately loose (grace 120); a 4-5 month-old max month is normal.

• Service classes F/G/L/P are all in the roll-up — never "clean" by

filtering classes, that breaks the cross-check. ~72% of ANC freight is

scheduled all-cargo, ~28% charter.

• FAI cargo is charter-driven and genuinely spiky (20× range observed:

0.4M–11.2M lb/month) — bounds are wide on purpose.

• Socrata mirror history starts 2014-01. A 1990–2013 deep backfill

exists at TranStats via a session-cookied DL_SelectFields.aspx POST

(table FMG) — one-time manual job, queued with the steward.

• No app token needed at ~2 requests/month; $limit=50000 a
