Vueling vs Vueling-marketed-by-BA
Take, for instance, VY1812 (BCN-MUC), look at 21 March. For that flight, if I'm reading Skyscanner right, then:
VY operated and VY marketed is £40
VY operated and BA (or indeed IB) marketed is £66
What exactly would one get for the extra £26?
Could this be a model for more BA s/h routes?
