More data points on my R1 DL-plated ticket.
I just returned to AMS. Today I called DL and changed the flight AMS-RGN to a later date. The agent said there is no availability on CI's AMS-BKK flight (which I don't think is true, since I can still book them on delta.com. I guess Delta is blocking CI for some unknown reason somehow). So she booked me on a KL flight.
After 5mins the ticket is reissued, and the validity of the ticket has been renewed to 30DEC13. It seems that I can make more changes later
