I tend to agreed using the older A330 airframe re new purchase as there are some routes to the Spanish resorts and indeed probably Turkey / Cyprus where that carrying capacity at certain time of the year would be useful. Indeed I noted a Conder A330 today in Palma but you don’t need that lifting capability year round apart from maybe to the Canaries.
Jet 2 have a good history it seems with older aircraft so does the new airframe bring other advantages in either fuel burn or something else which makes a new purchase advantageous?
