So I'm going to Europe on one of those fabulous 50 cent flights from US Airways, but my dad is joining up with me in Ireland (and I'm flying into Frankfurt). Despite my history with Ryanair and getting those even cheaper €0.01 flights, the Frankfurt to Dublin is expensive and requires an airport change in Germany. I noticed it's far cheaper to book a multi-leg to Dublin for my dad from the US, back to the US, but then also throw in my ticket the next day from Frankfurt on the same itinerary. My father and I have the same name, will this work?

Thanks!
