Great Sphinx Opening Hours (Not the Airport)

If you're asking about visiting hours, you likely mean the Great Sphinx monument on the Giza Plateau, not Sphinx International Airport — the two share a name but are unrelated. The Giza Plateau (Pyramids and Sphinx) is generally open daily from early morning until early evening, with slightly longer hours in summer; a paid entry ticket is required, and it's worth checking the current times and ticket prices on an official Egyptian tourism source before you go, since hours can shift seasonally.

If instead you meant the airport, Sphinx International Airport operates flights across normal daily hours in line with its scheduled departures — check your airline for terminal opening times ahead of a specific flight.

As with most Egyptian airports, it's worth arriving at least 3 hours before an international departure and around 2 hours before a domestic one, since security screening and passport control can take longer at busier times.
