The load factors are averaging roughly a passenger load on both an outbound and return flight
LCY does indeed have up to 3 flights a day to IBZ in July - Sept tremendously popular !!
I do agree that SOU has been hit badly by customer reaction to travelling abroad and Govt decisions on green / red list countries, but many over UK airports have seen good returning load factors to the Med
BA and SOU have done a lot of advertising and promotions for the flights , BA dropped many of the fares heavily but still pretty grim loads on some routes though
Good to see BA returning and keeping the faith
