Simply state how long the flight was, the departure and the arrival airports, and the aircraft used in the flight. You can also provide pictures during that flight, but it isn’t necessary.
I’ll go ahead…
I flew a FedEx Boeing 777-200F on a transatlantic flight from KJFK (John F. Kennedy Int.) in America, to EGLL (Heathrow) in the UK.
The image is me descending from FL360 over the UK coast at dawn.
Continuing here wouldn’t be bad? ;)
The thread linked below is very similar to yours, and I’ve seen people post about their flights being shorter than 30 hours on that other thread even if the title says it to be more than 30.
Then we have a precise replica of yours too, already existing :)
