Sorry for the disjointed post - I didn't realize Larnaca couldn't take jets initially:
'Larnaca Airport was hastily developed towards the end of 1974 after the invasion of Cyprus by Turkey on 20 July of the same year, which forced the closure of Nicosia International Airport. The site on which it was built (near the Larnaca Salt Lake), had been previously used as an airfield in the 1930s and, subsequently, as a military installation by the British forces. Larnaca International opened on 8 February 1975, with only limited infrastructure facilities and a prefabricated set of buildings comprising separate halls for departures and arrivals. The first airlines to use the new airport were Cyprus Airways using Viscount 800s leased from British Midland and Olympic Airways using NAMC YS-11s. Initially, the runway at Larnaca International was too short for jet aircraft.'
From the Wikipedia article on Larnaca
I seem to remember that RAF Akrotiri might have been used as a temporary airport but that might have been for UN Military traffic and families only.
