Sphinx Airport ICAO Code

The ICAO code for Sphinx International Airport is HESX. Its IATA code — the one you'll see on boarding passes, baggage tags and booking sites — is SPX.

ICAO codes are four-letter identifiers used mainly by air traffic control and pilots rather than passengers, while IATA codes are the shorter, three-letter versions used throughout the travel booking industry.

If you're searching flights or checking schedules, SPX is the code you'll need; HESX mostly comes up in aviation databases, flight-planning tools, or if you're looking at technical airport information.

Once you've confirmed your flight code, the next thing worth locking down is ground transport — Sphinx Airport runs fixed-price, licensed transfers to and from HESX/SPX across Egypt.

Airlines, airports and flight-planning software use ICAO codes internally, so if you ever see "HESX" on a technical document or aviation database, it refers to the same airport as the more familiar "SPX".

If you're filing or reading a flight plan rather than booking a ticket, HESX is the identifier you'll encounter; for everyday travel purposes, SPX is all you'll ever need.
