In order to see such a story, someone would have had to do contact-tracing of a large number of people with covid back to a single flight they all were on. Given the haphazard nature of contact tracing (in the U.S. at least) it is quite plausible that large-scale transmission events on airplanes are happening but simply aren't being noticed because we're not looking for them.

That said, the ventilation in planes is pretty good, and if everyone is wearing a mask it's equally plausible that air travel is relatively safe.
