They will absolutely blow out our margins and wipe out our yields trying to send legacy marketing departments into a retreat on their terms to keep remaining routes as profitable as has been expected. Its just a London flight. OK a couple from a couple markets. OK also Ireland. OK also Paris etc etc. If successful, other LCC's will join in and a couple years down the road the yearly seat dump on once lucrative markets, especially lay flat at a fraction of the price, will be staggering.

Its already a war of attrition. The apparent capacity-war/rational growth truce the industry had during the 2008-ish doldrums is over. Gordon Bethuns once said "you're only as smart as your dumbest competitor." Lose money fighting them now, or lose far more fighting them later. If the 321 XL-Whatever is the best weapon to fight back, great. If counter dumping with widebodies makes more sense, awesome. But it can't go unanswered and on their terms.
