So back to the original point. If EZY don't serve BHX-Spain then Norwegian (remember this is their thread) then they might be seeing RYR/EXS as a major threat to them. RYR is obviously a challenge for its lower fares, but i would have thought they could compete with EXS's fare level at least.
And for the catchment size, i would have thought the market could afford 3 main players (at least until MON went under)
