The Portuguese airline using a Boeing 737-300 to Faro, Portugal was iirc SATA (Azores)
and Thomsons used mainly the Air Europa 737-400 for quite a while.
Yes Spanair also did PMI and IBZ I recall 2004 A320's and MD-83.
Iberoworld with the A320 from 2004 (became Evelop and now Iberojet!)
I saw Iberworld's A320 depart and land on 02 - not a common occurrence, as the wind is usual in the other direction.
SOU 02 threshold
Azzura A320 first visit of this aircraft to Eastleigh in 2003
Austrian Arrows and Tyrolean CRJ-200's were seen 2006 - on INN or SZG summer charters>?
So the mainstay has always really been the 737-200/300 and 400
plus the A320 and 757.
Now the EMB Jets rule along with some A319/A320.

As an aside I have just seen some nice photos of BMA C-4 Argonauts at Eastleigh 1966/67 on charters, plus Air Ferry DC-4 and DC-6 and BUA and Cambrian 1-11's.
Transavia Caravelles and 737-200's seem to frequent too.
Seen at SOU Aerolineas Argentinas Boeing 727-287 LV-MIM leased by Lineas Aereas Canaries for summer 1988.
