48. (1987) Only one airline operates between North America and London utilizing three different types of wide bodied aircraft on the same route – each built by a different manufacturer. Identify the airline and the city it serves London from with its three different types of widebodies. And what the heck - you might as well identify the aircraft types as well.
Wardair has been correctly identified with 747, DC-10 and A300 flights out of YYZ. This question remains open to other possibilities if you wish. I'm happy to check them out.
I apologize got the delay in getting back to this question. In reference to WHBM's possibility of B-Cal operating three different widebodies on the NYC-LGW market, my OAG - which dates from November 1987 - does not reflect any service on this market from B-Cal. In fact, a check of the airline flight itinerary listings does not show B-Cal operating any service to North America. BA took over B-Cal in December of 1987. I was surprised to see however that per my OAG at least B-Cal had ceased operations to North America. Could the OAG possibly be in error?
