17. Boy, this could be anybody, as many of the major European carriers ran to South America stopping at Madrid. I'm guessing it's not Iberia or LAN, but someone stopping at Madrid on the way.

Let's go as a starter for British United, with their VC-10 which had taken over the route from BOAC Comet 4s a couple of years previously. In which case 5 intermediate stops would be Las Palmas, Rio, Sao Paolo, Montevideo and Buenos Aires. These flights ran twice-weekly, but alternated between Madrid and Lisbon, once a week at each. They crew changed twice, at Las Palmas and Sao Paolo, the crew dropped back three or four days each time, and were away from home for three weeks. At Las Palmas they used the same hotel as the "milk run" BUA One-Eleven which night stopped there on its once-weekly run to and from the west coast of Africa, and from the account of a nowadays grandfather, but then junior FO, when they coincided a good time was had by all ...

If it's not BUA, ignore all this bit.
