"RED WINGS" Easy did not sell any aircraft to Monarch, let alone A320s, they did not own them in the first place.
The a/c Monarch have taken or may take are A321s and the ones todate are owned l believe by GECAS.
As pointed out these a/c are built to a BA build spec and do not match Easyjets current fleet.
Hope this information is of help and backs up what "ReallyAnnoyed" posted.
