Luton, Birmingham, Bournemouth, Manston, Gatwick, Manchester & Cardiff (& maybe a few more?) all accepted Heathrow or/and Stansted diverts.
However, is there any truth in the rumour that several Luton inbounds also had to divert due to the LOREL & ABOTT holds being full (of Stansted inbounds) & thus couldn't get anywhere near Luton? I know East Midlands & Bristol both accepted Luton diverts
