The Pan Am (ex-Air Florida) 737-200 that I flew MIA-TPA on in August 1988 was in the new scheme, despite still having the full Air Florida interior. I remember it was the only Pan Am 737 in MIA that day in the new livery, although all the 747s and 727s (plus the A300s which never had the old livery) were in the billboard scheme.
I never identified the aircraft I flew on that day...Can you help me to? How many of Pan Am's ex-Air Florida 737s were painted in the new scheme in August 1988?
Looks like N67AF probably was;
