BA hardly in retraction mode when they're refitting all their LGW fleet to have a lower cost per seat than Norwegian.
Oakland isn't gone? Reduced by 1x weekly, same as MCO and they're relaunching LAS from LGW so more competition for DY.
Pax are flying on price solely in economy that's the problem with the entire industry at the moment, pax don't want to pay much for flights and hence the cuts, cuts, cuts by the likes of IAG in order to keep demand and survive. Welcome to the ryanairsation of the long haul industry and will further continue with the introduction of the A321neo and A321LR.
Hopefully Aer Lingus uses one of those A321LR at Cork etc, will mean a proper US primary airport connection, not the Frankfurt Hahn of the east coast of the USA as you see with Norwegian.
