While their may be no immediate alternative bar the ageing but ubiquitous 75 isnt a serious problem with both the Avro and the ERJ the fact they cannot carry any significant cargo compared to a 738 or 319/320. I thought cargo was important in being able to retire the RMS ship that served the island so what would happen if they accept that only the Avro ( a long way for one) or an ERJ are the only options but there is no material cargo uplift
