Looking to book in October, anyone know when tickets will be available to buy?
I just checked Hahn to Dublin on Oct 19th. You can already book them online. Keep in mind that the website will be closed from Feb 22nd to 25th! See my post on just that topic.
Susan, regarding Ryan Air and other inexpensive airlines, I suggest looking for the routes on the day you wish to travel as soon as you can. If not yet available, check back every few days until you see the it available.
The reason for this dilligence is that these airlines have a unique ticket pricing program. The first people to buy tickets get them the cheapest. As the plane fills, the prices go up. The longer you wait to book your flight, the more expensive the ticket will be. Early bird will get the worm here.
