I'm going to go with CDG, SXF and MAD
I hope to god they dont go for CDG. Theres already 6 daily flights to MAN, with BE/AF, do we really need more frequencies/carriers on the route?
SXF- One of the biggest gaping holes in the MAN-Germany market, so would be a very welcome addition.
MAD-Their north west monopoly on MAD is just about to be threatened with RYR's MAN-MAD. A counter attack maybe? Even if it does effect LPL's loads, its better than loosing out completely?
MXP- Even though its not served from LPL (from the '3 routes already at LPL quoute'), MXP airport loaded twice daily Easyjet MAN-MXP flights into their timetable 2-3 years ago, so, maybe they are ressurecting that idea?
With that, my guesses are MAD, SXF and maybe LIS for when that base opens (as LIS is also a LPL route)
