More Ryanair represents a lot of eggs in one basket to me. And if they were really serious at BOH it would have been a base 2-3 years ago. Have you noticed that most of the recent announcements are only 3x weekly services? Clearly Ryanair think that there are fatter routes out there for them to focus on.
Easyjet would be a real coup - the 3 largest LCCs in Europe (Ryanair, Easy and Air Berlin

) all at BOH!
