G-YMMB is "supposed" to be back at LGW tomorrow, but it has quite an interesting schedule. It's been partying in Malaga, en route to Accra. Now needs to get back to LGW for a flight to Jamaica. Not sure if it needs to drop passengers at LHR first on its return, or if it can go straight to Gatters.
Depending on the reason for the diversion, there looks to be a fair bit of EC261 compo here too.
