Yup AE's N602FF 747 Fat Freddie leased from Tower Air was one of them, plus in 1989 AE also leased N751PA B.747-121 from Orion Air (USA) which IIRC Airtours also operated.
You can also add in the Lion Air 747-100's leased from Cargolux (seen st times with both Lion Air and Orion Air titles) that flew for both Airtours and International Caribbean.
All the aircraft were basically white.
For AE and AIH the old crates could be seen flying anywhere from Gatwick or MAN to Orlando, or to BKK (AE), Palma and TFS
AIH decided to upgrade and leased a nice Rolls Royce 747-219B from Air New Zealand
AE had RR MD-11's on order but they went bust 1991.
