I note that LCY is asking for feedback on its website about possible flights to DUS, HAM, BUD, VIE, FCO and OPO. IIRC, with the exception of OPO and BUD, all have been served in the past.
Maybe some hope for new routes (provided that the rioters do not flatten LCY tonight....
)
Realistically, only BA would make sense on them after Star Alliance failed on DUS, HAM and VIE.
