The Birmingham rotation seems to be squeezed between a morning rotation to Berlin and an evening rotation to Faro.
ps Does any one know if those marvelous A321s still transit Cork, or if the fourth A320 will be a 321 instead?
No idea about the new aircraft, but I suspect it won't be a 321.
Currently, the only scheduled visit by an EI 321 is in the summer timetable when one of the Heathrow flights is operated by a London based plane.
