Sorry to hear about not remembering.

BOS-CDG were probably L-1011's. They were later in the 80's. In the summer, 1984, several JFk-LHR flights were L-1011's but not all. By around 1988, BRU-JFK flights were L1011-200's.

BRU was served via AMS, including sometimes with one of 3 747SP's. For a short time in late 1986, there was BRU-LHR-JFK on a L1011. Around 1987, BRU-JFK became non-stop.

I liked the L1011's. Those were my favorite planes until the A340 came out. The 747SP wasn't bad.
