Sorry to digress a bit more from thread subject, but is that entirely correct? I flew as passenger from Gatwick to Houston and back in 1991 with BA. This was rumoured to have been a former British Caledonian route, and was still using the DC 10
A search now suggests BA continued with most of the DC 10s until 1999 (maybe one to Caledonian in 1993 and came back), the last sold 2001
The BA, British Airtours, BCAL, BCAL Charter, and Caledonian Airways (1988) history
is quite a topic to get one's head around LOL.
BA had bought BCAL in 1988 (who had the DC-10 30 fleet, and had also the 2 BCAL Charter DC-10 10 series).
BA inherited and kept the DC-10 30's, and the -10 series (bought by BCAL ex Laker in 1982 for holiday charters in a tie up with Rank) were already moved on in 1986 to become Cal Air International, which was renamed in 1988 as Novair International, because BA had renamed their own charter airline British Airtours (KT)
to Caledonian Airways (CKT) also in 1988.
The 'new' Caledonian Airways CKT (owned by BA) inherited the old KT fleet of L1011's, a 747, and 737's.
The sole 747 flew for both CKT and BA then it was sold to Virgin in 1990.
CKT soon expanded with new, and ex BA and AE 757-200's and added more 737-200's.
They also had entered the long haul holiday market to Banjul, Mombasa, Goa, The Maldives, Orlando, LAX, Mexico, and to the Caribbean so they obtained from BA on lease a couple of the ex BCAL DC-10 30's,
plus leased in some others from other airlines, such as G-GOKT G-LYON G-BWIN and OO-LRM.
in 1995 BA had sold Caledonian to the Inspirations Holiday Group, and the carrier was later transformed along with Flying Colours as JMC Air as part of Thomas Cook airline grouping in 2000.
It was under the Inspirations Holiday Group that the 3 new Airbus A320's were leased by CKT (which is the subject of this Thread)
Yes LGW-HOU was a BCAL route flown by the DC-10 and the 747.
