One thing that seems to have become a norm in these times of COVID-19 are unsuspecting cargo flights. What do I mean by that? Well, for those of us that follow traffic into Fort Lauderdale will know that the only Emirates flights they we (used to) get were the 5 times a week Boeing 777-200LR from Dubai that we as a family also traveled on. So, when Boeing 777-300ER flights suddenly started arriving once or twice a week, we wondered why was going on. The explanation given to us - cargo - using an empty aircraft to transport cargo to and from Dubai.
This has become a norm for a few pilots that I follow on Twitter - British Airways has done exactly the same from London to a couple of cities in China - flown an empty 777-300ER outbound and filled it with cargo back to England.
For the latest flight, it was an added bonus as Emirates decided to send us one of their 2020 Dubai Expo special schemes which I managed to catch on some decent light as it headed back to Dubai.
