Wiki updated as of today's movements across the fleet. Gatwick sees the lowest number of stored A319/A320's since the pandemic began with only 10 aircraft in storage there currently. A few of the LHR B777's are marked as in storage has they haven't flown the last 6 days or so, but I would expect them to come back into service this weekend, so if they are noted back in the skies, please feel free to update. LHR also sees the largest fleet number in a long time based there with almost 200 aircraft back at home base.
