Every Landing Always Late (El Al backronymic nickname)

El Al Israel Airlines Ltd (TASE: ELAL), trading as El Al (Hebrew: אל על‎, “To The Skies” or “Skywards”, Arabic: إل عال‎), is the flag carrier of Israel. Since its inaugural flight from Geneva to Tel Aviv in September 1948, the airline has grown to serve some 45 destinations, operating scheduled domestic and international services and cargo flights to Europe, North America, Africa and the Near and Far East from its main base in Ben Gurion International Airport.

El AL is often teased with the suggestion that the letters mean Every Landing Always Late. But El Al doesn’t mind and neither do the passengers. El Al remains the world’s most unhijacked airline.

Wildcat strikes were a way of life with El Al, which departure-lounge wits insisted stood for “Every Landing Always Late.”

Yet the frequent delays meant that El Al still appealed mainly to air travelers sentimental about its ties to Israel. With good nature, they joked that El Al really was an acronym for “Every Landing Always Late”, and the Constellations were called the “El Al Cancellations.”
