I'm trying to change the last leg of my excursionist trip from ORD-DTW to LGA-AZO. If I go into my ticket and try to change it, the LGA-AZO flight I want doesn't show up (9am-137pm). If I try to book a standalone award ticket, it shows up no problem. Not sure if this is excursionist related or not, just thought it was odd and a bit frustrating.
