I believe the following booking is legal as it has only one stopover on the way back. EWR-SEA(UA), SEA-ICN-TPE(OZ) (destination for 3 days), TPE-NRT(Stopover via OZ for 5 days), NRT-JFK (NH in Y or OZ in C ). There is about a two hour connection at SEA. Am I doing something wrong? It won't price on UA website. Errors out. I want to try and book it if we go with the NH direct in Y. The other option is to use USDM if we want the long way in C. Am I misunderstanding the rules or is it just UA's website forcing me to call in to the agents?
