sentences:  The company charged a very low £5 one-way fare on these night-time services, which were marketed under the "Moonjet" trademark.This move, which was modelled on the high-frequency-low-fares operation run by Pacific Southwest Airlines (PSA), the original "no frills" airline, along the busy San Diego—Los Angeles—San Francisco air corridor in California, boosted passenger numbers and profitability on both routes.During that year, larger capacity, longer range and more fuel-efficient Boeing 707s replaced VC10s on BCal's South American routes, where the 707's greater range enabled the airline to run non-stop flights between London Gatwick and Rio de Janeiro, as well as on the West African trunk routes to Nigeria and Ghana.
