A family member (no status on either US or AA) has given me his account
I am Star Alliance Gold (UA and TK) and AA Gold (through 2/14)
I was surprised to discover when trying to book an award trip for early February that all the flights offered for for my itinerary were AA flights.
When I went as far as the confirmation page, and clicked on baggage policies link, it noted that the bag fees were waived for "Star Alliance Gold"! Not sure how that is going to work on an AA metal flight on a US ticket.
I also noted that when I put in my AA Gold number in the dummy reservation, it wouldn't let me select any seats.
I would have gone ahead and ticketed and seen whether I could indeed get More-Room seats by calling AA once it had ticketed except that I read the fine print and was surprised to see that there is no 24-hour refund rule for award tickets, but it costs you $150 to re-deposit.
I'm hesitant to pull the trigger not knowing whether I indeed get a free bag (am delivering a Christmas present that will probably weigh 40 pounds) and whether I will get to choose premium seats for free.
Any wisdom here? If this is covered elsewhere, mea culpa and feel free to refer me
