Jet 2 will not require these aircraft until the 2020 summer season, with a limited number prior to that for crew training.
I would not put any mind to where these aircraft might be heading.
They will need to go into storage, ideal climate not being in England or Ireland.
Prior to delivery all 7 aircraft will require a heavy maintenance check to clear them for 24 months (what was a "C" check), as is the norm and a paint job.
This can be anywhere in the world and is a lot cheaper outside of the UK.
