We have to say that AA’s premium economy is a very nice upgrade however it comes at hefty price. We paid the extra $3000 for two of us to upgrade for a 14 hour flight from DFW to PEK in June and then noticed that AA gives away premium upgrades in flight ! During our flight out, AA gave away a seat to a non rev and then on the return trip they gave away a seat to a passenger. We watched as the economy passenger simply moved from economy seating to premium economy, ie a free $1500 upgrade. When we contacted AA Advantage their response was, ‘ unfortunately, I am unable to provide an answer or an explanation, as I have no idea what the other passenger’s situation was.’ So, AA wants to charge ‘some’ passengers $1500 to $2000 for the upgrade and yet others get it for free? And AA doesn’t compensate or explain to those who identify an issue on even a premium service? Why even communicate w/ AA when AA will ignore even customers paying for a very high priced premium service? Talk about feeling like getting ripped off and ignored. And AA expects return customer? Seriously?
