You can print your passes between 15 days and around 2 hours before the flight. I don't get your point.
I've flown with Ryanair plenty of times and, if you are able to ignore the constant bugging with booze/parfums/car rentals onboard and can stand the small seats, they are the probably the best thing that there is.
it's 7 days, not 15. the point is that if you're on a trip longer than 7 days you have to print them while on your trip, which might not be easy.
For the life of me, I'm sure it is (or at least it was) 15 days. And yes, printing it while on your trip can be a major nuisance (happened to me once; it was not a nuisance for me on that trip, but depending on where you are, yes it can be).
Is there a Dealing-With-Ryanair-As-A-Service company out there? It would be hilarious for someone to figure out all the tricks of Ryanair and then offer, for €5 or something, that they will make the plane reservation and text you the moment you need to do the things you need to do, and otherwise clarify the process.
I took ~100 Ryanair flights for a while, and I can't see the benefit of this. You learn quick enough how to avoid all the charges and you don't pay more. Why would I pay €5, when I know how to get the flight for €30?
Just remember that with Ryanair, simple is not an option unless you pay and pay and pay and pay.
Example: Printing boarding passes a few days ahead: not possible. Oh, unless you pay for reserved seats. Otherwise feel free to wait until a few days ahead of departure, remember to check in, or you'll be hit with another charge at checkin.
Source: Traveled w/Ryanair this summer with my family. The whole process was so annoying that I made it a priority not to give them a single € extra, even if that meant spending more than an hour at a slow internet café somewhere to print boarding passes for our flight home.
