I missed the overnight and had the wrong flight when I checked PHX-MAD
Availability can vary on sectors depending on where you are coming from or going to with connections
A-B may have U1 C1
A-C via B might show U0 C00 for the same A-B flight
For ABQ-MIA on 6/10/19 , AA2335 connecting to AA2550 connecting to AA68 does show C1 for DFW-MIA and MIA-MAD , so surprised if unable to upgrade
