Carol is correct. The key to an airline routing with a stop or stops is having the entire ticketed route on one PNR. Now any problems have ownership. If you break the trip up on different tickets you set yourself up for a world of hurt. I once had a friend book a crewed charter for 21000 dollars many years ago. JetBlue had a JFK to SJU roundtrip for 189.00. He jumped on that against my advice and booked a separate connection on CapeAir. His family of 4 took that routing and another family of 4 booked American straight through for about 250 more than the combined JB/CapeAir. He saved 1000.00 dollars. Then the Snowstorm hit NYC. His JB flight was cancelled. The American flight to SJU was also canceled but AA rebooked the family to MIA SJU EIS. They got in late that night but boarded the charter ontime in the morning. He got there late day two of the charter and only after paying for a hotel in SJU and 1100 for 4 one way tickets to EIS.
On the plus side the one family enjoyed the extra shrimp cocktails and Filet at the first nights dinner!
