i suspect with most of the short haul and domestic ops scaled right back from today for the forseeable future there will be more use of the DHL network by BA and full use of the A300F/B757F DHL fleet. Yesterday a DHL A306F did an Arlanda-Luton LTN-Arlanda return flight.
Interestingly and i dont know who is booking these, European / Maleth are doing a package of A340-600 flights Bournemouth-JFK-Bournemouth the ex Virgin machines
