22 years ago
I was on the last britannia flight from Hong Kong some 22 years ago - I think that was a 742. 3 standby pax and the crew. Conclusion: low load factor, zero revenue.
While thinking of load factors .. if a flight is full and id pax are seated on jump seats - the load factor would be above 100% coz jump seats are not used in the calculation of actual seats... 19 years ago from Shanghai to Heathrow on a jump seat - good old times.
