US States Airport Codes: IATA Codes by State & Travel Info
Find major United States airport codes by state, learn the difference between IATA, FAA, ICAO and DOT identifiers, and avoid common booking mistakes like choosing the wrong Washington, New York, Bay Area or Cincinnati airport.
What are the US airport codes?
For normal travelers, US airport codes are the three-letter IATA codes used in flight search, tickets, boarding passes and checked-bag tags. Examples include ATL for Atlanta, LAX for Los Angeles, ORD for Chicago O’Hare, DFW for Dallas/Fort Worth, JFK for New York JFK and LAS for Las Vegas.
Use for booking
Use IATA codes when buying airline tickets, checking flight status or confirming baggage tags.
Airport live checks & travel tools
Use current local conditions, official live-status links and planning calculators before you travel. Airline gate, terminal and flight times can change; your carrier remains the final source for flight-specific details.
Live flight center
Check the airport's official flight board, then confirm any last-minute gate or timing change with the airline.
Current airport-area weather
Useful for planning your trip to the airport. This is model-based local weather, not an aviation METAR or an airline operational forecast.
Quick official checks
Open the source that matches the decision you are making right now.
When should I reach the airport?
A planning estimate based on flight type and common time buffers. Always increase the buffer for severe weather, major holidays, unusual airport alerts or airline instructions.
Connection-risk checker
This is a planning heuristic, not an airline minimum-connection-time rule. International arrivals that require U.S. entry processing, baggage claim and security can need substantially more time.
Parking cost estimator
Uses the airport-specific rates stored in this article's configuration. Rates can change; verify availability and final pricing on the official parking page before driving in.
Passenger pickup readiness
Landing time is not curb-ready time. Add time for taxiing, deplaning, baggage claim, customs when applicable and walking to the correct pickup zone.
Use for official US airport lookup
FAA identifiers cover many public, private, heliport, seaplane and general-aviation facilities that travelers may never book.
Use for aviation data
DOT/BTS airport IDs help analysts track airports even when a code changes or is reused.

WYIATA vs FAA vs ICAO vs DOT airport identifiers
Three-letter code used in airline booking, tickets, baggage tags and travel apps. Example: LAX.
US aviation identifier used by FAA systems. It may match the IATA code at major airports, but it can also identify many non-airline facilities.
Four-letter international aviation code used in flight plans, dispatch and weather. Many mainland US airport ICAO codes add “K” before the three-letter code, such as KLAX.
Data identifier used for statistical analysis. It helps avoid problems when airport codes change or are reused.
Common US airport-code mistakes to avoid
New York airport confusion
JFK and LGA are in New York. EWR is in New Jersey but often appears in New York City searches. Check your ground-transport cost before booking.
Chicago airport confusion
ORD and MDW are different airports. A self-transfer between them can require a long ground transfer and another security screening.
Washington-area airport confusion
DCA and IAD are in Virginia. BWI is in Maryland. All can serve Washington trips, but they are not interchangeable for timing.
Cincinnati airport state confusion
CVG serves Cincinnati but is located in Kentucky. A state-by-state airport-code list should treat physical location and city market separately.
Orlando airport confusion
MCO and SFB are separate Orlando-area airports. Rental-car pickup, shuttle options and drive time can be very different.
Bay Area airport confusion
SFO, OAK and SJC can all appear for Bay Area trips. Choose based on final destination, not just airfare.
