The avherald report (very informative as ever) shows a standard departure from Tenerife South going nowhere near La Palma. I wonder what the routing of the aircraft was on its arrival on the previous flight. My experience is that the arrival would take you much closer to the rather interesting bull's eye shape cloud forming around the volcano caused by a temperature inversion around 15,000 feet. If this is a based aircraft or one frequently in TFS it could be a precursor of a wider problem. I imagine a number of airlines will be inspecting engines of aircraft that have been there recently. Hopefully it is no big deal. But having been through the Icelandic grounding I am surprised that so far there seemed to have been so little impact.
