# What airport is LAS?

**LAS is: Harry Reid International Airport**

Las Vegas, United States

## Why the code is LAS

The first three letters of Las Vegas.

The airport authority or a contemporaneous record states this directly.

## The airport

- **IATA code:** LAS
- **ICAO code:** KLAS
- **Airport:** Harry Reid International Airport
- **City:** Las Vegas, United States
- **Code origin:** Documented

It was McCarran International until 2021, when it was renamed for Senator Harry Reid; the code did not change, because LAS was never derived from McCarran in the first place. Slot machines in the terminal are a genuine oddity — most jurisdictions do not permit gambling airside.

## The other code, KLAS

Every airport has two codes. The three-letter IATA code, LAS, is the one on your boarding pass and your luggage tag, and it is assigned for commercial use. The four-letter ICAO code, KLAS, is the one pilots and controllers use, and it is assigned geographically: the first letter or two identify the region, so every airport in the same part of the world shares a prefix. That is why KLAS looks nothing like LAS.
