Given BA is showing cancellation of 6 routes out of LGW incl Atlanta / Brussels / Toulouse / Geneva / Zurich / Marrakech.....most I think previously announced.
?? ATL and TLS moved to LHR
GVA and ZRH(?) will be back for the winter
RAK wasn't a BA route and it went when GB went orange
BRU is a BA codeshare route operated by Brussels Airlines.
