Hello, can anyone clarify or tell me if it’s still allowed to change your flight free if you originally booked Qsuite and then it changed to non-Qsuite (in my case same route / day just the flight earlier in the day)?

I have a trip to the Philippines booked, originally it was Qsuite coming back but the MNL-DOH segment has changed to non-Qsuite on the 777…however the flight earlier still shows Qsuite.

I won’t do anything now because something similar happened with my flight to MLE, the last few days or so it went through 2-3 changes. But anyway just in case this stays, am I allowed the free change to the earlier Qsuite flight?
