Same thing happened to me, agent pushed it through and ticket was confirmed. it was for a flight 3 days out. However after i ended the call, ticketing wouldn't issue ticket and so booking expired. another agent said I just have to wait 7 days. but based on feedback here about earning, since I'm going to be transiting through FRA next month, i'll just make sure to make some purchase there to earn some points and hopefully it works after.
