You have me thinking now (could be a worry)
I am already AA Plat but could get all 6 teenagers to do the challenge and perhaps throw in a day trip from LAX-SFO on our trip to get everybody over the 10K threshold. Thinking the plat bonus could make this worthwhile. Especially with 'family transfers' of points in the future.
Was going to sign up 2 of them as QP members before we leave to get all of us into the AA clubs during our trip. But the ongoing value of AA Plat to give all of us individual lounge access would be very handy. The 'kids' probably won't requalify next year, but even when they drop down to Gold we'll get a handsome bonus on their travel (however infrequent).
Thinking, thinking, thinking ...ummm can I convince teenagers to get out of bed early to flyto SFO for a few hours? One I can bribe with Ghiradelli chocolate atleast! Has anybody ever had 7 family members all on a Platinum Challenge at once? Is this likely to 'concern' AA?
