M-D - if you think half a dozen posts on Pprune is a hoo-haa, you need to get out more...
I think the point is this - airline with little local market presence launches a BCN service for next summer, and then offers at relatively short notice a series of flights for Xmas and the New Year.
The second of these flights is operated by the largest a/c in their fleet. Knowing the LCC dislike the flying around half empty a/c, the question is why? is it due to demand (which would be a "quite interesting" pointer for the summer season) or another reason? Even if it was "always scheduled", the same question applies - why?
I don't think anybody posting here wants anything other than the new Vueling service to be a success
