I always liked the Braniff scheme, sadly I only ever saw "Big Orange" at Gatters and they'd gone by the time I went to the US. The revamped scheme from around 1980 wasn't as nice. CP Air, another belter of a scheme.
There was another South American outfit often in evidence at Miami which had some ex Alitalia DC-8 43s - their scheme owed something to the former owner as I recall! ARCA? Something like that...
Yup Arca Colombia:

Apparently a 51 rather than a 43...
