As much as I like the aircraft, how much life does the A300 have left with Monarch. Over the past few years, these aircraft have spent most of the time transporting the masses to and from Greece, Turkey and Egypt. With the Olympic Holidays contract 'lost', and the political unrest in Egypt severely denting demand for flights/holidays to the country, the A300s and A330s are now spending most of their time on scheduled flights to Cyprus, Spain and the Canaries.
I'd hate to see Monarch get rid of the A300s, but with their change in strategy towards becoming a scheduled carrier, surely they will be surplus to requirement. The few scheduled flights that do warrant 350+ seats could probably be covered by the A330s, which have also been fairly redundant this summer.
