Nice shots. The Aerolineas Argentinas MD80 runs a European shuttle service for the airline out of Madrid connecting to their trans-atlantic Beunos Aires service.

I think the white ATR is possibly a Swiftair one.

Right, the MD-80 is based in Madrid because Aerolineas uses Madrid as a mini-hub to move passengers to and from Madrid. Another MD-80 from Aerolineas is operated by Air Plus , both airlines are owned by the same family so they trade planes often.

And, right too with the ATR, EC-JAD is from Swiftair
