SpringheeledJack. Yes, I mentioned the Aer Lingus 737s in my opening post. I gather they also used to send their 707s and 747s to the Mediterranean when they weren't crossing the Atlantic or flying for another airline, as they often were. I don't know if their 1-11s got a slice of the Mediterranean market; Autair, BUA-Caledonian, Airways Cymru and others did.
Which reminds me, although the 732 was clearly the king of the Med thirty-plus years ago, let us not forget the other aeroplanes that were heavily involved too. The Viscount and Britannia, the DC6, the 707/720 and 727, the BAC1-11, the DC8, DC9 and DC10 and the TU134 and TU154. Lockheed TriStar. Then came the later marks of the 737, the 757 and 767 and Airbuses of many kinds. And the MD80 series.
