earlier this week i had to book a one way SMF-SBN. the one stop via ORD was twice the price of a two stop via LAX and ORD so I booked the two stop with the idea to SDC onto the one stop if inventory opens up. however due to buggy .bomb, I had to trick it to get the desired itinerary by using multi-destination. will this booking method inhibit my ability to potentially SDC onto the one stop if inventory is open? all three flights are in the same fare class (S) and the layover in LAX is under 90 minutes. thanks in advance.
