TN ( Air Tahiti Nui) has between 4-5 aircraft all A340s. When VS ( Virgin Atlantic) started operations they had a single aircraft, a 747-200. SB ( Air Calin), the national airline of Nouvelle Calédonie has a fleet of 3 aircraft, 2 of which are widebodies.
A bunch of cargo airlines have small fleets of large ac, such as Cargolux which has 747-400 and 747-8
Corsairfly operates the 747-400. I think its the configuation with the most pax of any airline operation this plane
At the time Wardair was bought by Canadi>n, it was flying 3 B747-100s, 3 DC-10-30s, and 12 A310-300s. Retired 10 years before the purchase were 2 additional B747-200s, and 3 A300s. Since the retirement of the B707s in the 1970s, Wardair was an all wide-body airline.
Just because I stopped arguing, doesn't mean I think you are right. It just means I gave up!
