I am attempting to book a UA flight using SQ for the following routing: EWR-HNL (first leg)
HNL- LIR (stopover in EWR for 2 months before taking LIR flight)
The SQ agent is telling me that this is not a valid routing since I cannot do a domestic SO in EWR since my departure city is located in the U.S. (HNL).
Is this a correct? Or do I need to HUCA until I find someone that can book this properly?
