My latest post on where we are with Covid in England (likely at, or just after, the peak but it's been a big wave).

KP.3 is not a FLiRT.
FLiRT have a F456L and a R346T mutation. KP.3 does have a F456L mutation, but no R346T. Instead KP.3 has a Q493E mutation. Both FLiRT and KP.3 have sublineages with S31del, that make it faster.
KP.3.1.1 (S31del) might give this wave another boost when it becomes dominant.
