Should this still be the case? Does anyone else have a recent situation?

We booked an AAVacations package last month when there were cheap rates to Barbados to travel in Sept. For my return flt, I chose a departure @ 2:45 pm, via MIA, arriving back to LAX at @ 11:45 pm.

I have a phone message to call AA Vacations because of a schedule change. When I pull up my itin, it now shows my return leaving @ 7:20 am I would NOT have booked that. As best as I can tell, they have eliminated the MIA-LAX flight that night that we were on, so we were moved up.

Before I call, I have to ask my husband if he wants to cancel (because we had another trip come up that we are also spending $ on).

Wanted to check my options before calling them -- if we wanted to cancel/refund, are we entitled to because of this schedule change? Do I have to say I have a conflict with that? Or just ask for a refund? My 'conflict' is missing half a day's vacation & getting up @ 4 a.m.

Thanks
