Clearly there is much going on
1) Last time this went out to tender, there were separate tenders for Aberdeen and Edinburgh and Loganair declined to bid for Edinburgh
2) There have been talks with Loganair for the temporary operation of Aberdeen which appear to have been unsuccessful.
3) The two routes have now been packaged together and operational flexibility is now planned. This is a tender that has been designed with a particular airline in mind.
4) There aren’t many airline options!
