Also earmarked for B.O.A.C. are eight Britannia 300s (this model has a fuselage 10ft 3in longer and has a greater payload) and ten Britannia 300LRs (the 300 with additional tankage).

According to arrangement, it can seat from 60 to 101 passengers; or it can be used as a freighter or with passengers and freight in combination. It can fly economically at any height between 20,000 and 30,000ft, and the 300LR model is capable of maintaining regular non-stop services across the North Atlantic the year round.
