City spending

Houston Airport System (HAS)

The city's published checkbook records $6,156,538,651 paid out under this department across 102,648 payment lines and 1,640 named vendors, FY2018–FY2026.

Department name as the city's finance system records it. The city's budget year runs July 1 to June 30, so FY2026 means July 2025 through June 2026.

The city publishes this a few times a year, so it runs behind — the newest payments can take a few months to appear, and a fiscal year that has just ended usually isn't published at all yet. Treat the most recent year as incomplete.

What this does and doesn't show

These are payments, not a budget. The same ledger carries debt payments, bank and pension transfers and accounting reversals alongside what the city bought, so adding it all up doesn't describe city spending — which is why you won't find a citywide total here. What a named vendor or department was paid is solid.
Some payments name no company: the city files them under "GENERAL ONE-TIME VENDOR" or a bare asterisk — $617,266,200 across FY2018–FY2026, about 1.2% of all payments. Much of that is properly private, like legal settlements and housing assistance paid to individuals. Those payments aren't listed as vendors here because there's no vendor to list.
A department total here is what moved through that department's books, not its budget. Funds it administers on someone else's behalf are included.
