Whilst surface transmission is possible, it is at most a minor and most theoretical way that COVID-19 could be spread. The key thing is minimising contact between people where possible, what matters is how many times crew interact with passengers, whether they are wearing a mask and how close passengers are to each other, not if the crew member has heated your meal or not. But of course, airlines such as BA are never willingly going to reduce passenger numbers on a flight to facilitate this and nor do they appear willing to scrap J class at the moment because service itself could be an issue, so we get this pointless security theatre that makes some people feel better but doesn’t really achieve much instead.
