Duo will have to be clever to avoid becoming another JetMagic.
Their CRJs can't compete with the locos and the payload/range would probably prevent introduction of 'sunshine' destinations (although I am open to advice on this).
So, if my suppositions are correct, it's business-type destinations at business fares. That is likely to mean competing with BA and the majors to destinations like Brussels, Stuttgart, Lyons, etc.
How about a sprinkling of 'business' routes from Luton? Massive catchment area, less congestion than LHR, slot availability, quick turnrounds etc. And the only competitor will only go to 'big' airports like CDG, AMS, GVA & ZRH.
Think about it, Duo, we'd like to see you on the Costa del Beds.
