If this were to happen, DUB is plausible providing the current cap allows though the smaller airframe would make it difficult to complete with the likes of Aer Lingus/American/Delta/United. From a UK perspective the only realistic operation I could see is LCY, essentially a replacement of the BA A318 services pre-Covid. Anyone that would expect to see this at the likes of MAN, NCL or GLA I'd say dream on, but would like to be proved wrong.
