I had similiar query some time back. I am travelling From Leipzig [Altenberg]to Stansted with Ryanair with my wife and teenager all on same internet booking.We then travel on to Shannon with Ryanair.When I booked tickets we had no check in bags.I now wish to bring 1 bag to check in for the above flights.Will it cost me €70 to do this.€20 for check in bag at each airport and €15 for each person on the ticket to check in at each airport.If I try to check in the bag on line at this stage it gives me the charges for additional bags? Any help please!
