The Eilat Airport was reopened Thursday night two hours after it was ordered closed for security reasons.
The reopening was ordered by Israel Defence Forces (IDF) Chief of Staff Benny Gantz.
Although the IDF did not give any specific reason for the closing, officials in Eilat said that it was most likely connected to an assessment of increased terrorist activity in the Sinai desert, which borders on the southern port city.
Eilat has been targeted in the past by rockets fired by Islamist terrorists in the Sinai.
Sinai has become increasingly lawless amid the instability generated by the overthrow of Egyptian President Mohammed Morsi in early July.
The Israeli government is completing a fence that runs the entire length of the border, has stepped up military patrols and has in the past deployed batteries of its Iron Dome anti-missile system in the area.
