Not sure why EI use A319`s on the routes to Heathrow and Gatwick as any time I fly to London with them, the flights are pretty full!
Well since this is a rumour site, the rumour I heard it that they are using-up A319 airframe cycles on the short flights before dumping them in the Winter.
EI-EP[R,T,U] have all cycled through Belfast-basing in the past few weeks whilst EI-EPS is being flogged on Shannon to London.
