I'm gutted Aer Lingus are shutting Ork-ALC for the winter, not even one flight a week.
If you are prepared to fly with FR, just wait until the end of the week and visit their website. You may be pleasantly surprised and may be able to book for January or whenever else you want to go. There are lots of other ways to travel instead of AGP - MAN, LPL, DUB, LON who all have very frequent ORK and ALC flights whih would make a connection very easy.
