Thanks guys for getting back to me. I have business in both FRA and RIX so my routing is as follows DUB-FRA-RIX-DUB. I have booked a multi city reservation with EI for the DUB-FRA and AMS-DUB with separate tickets on LH on the FRA-RIX and Air Baltic for the RIX-AMS. I know I could book with KLM on a through ticket on the RIX-AMS-DUB sector but the one way ticket is €1400 approx. I'll take my chances on making the connection on separate tickets.
