I have just started searching for award space in Sep-Oct from CLT to somewhere in Greece. I am using United.com and I have found availability CLT-MUC-ATH on Lufthansa and Aegean but I keep getting the error message that the Aegean portion has magically booked up, yet when I go back and search it's still there. Is there something tricky about booking Aegean via United? I can dummy book the CLT to MUC part without problems but adding the ATH part mucks things up. Any suggestions on routing would be appreciated. Looking at 12-14 days wanting to hit Athens, Santorini and Rhodes. Thanks in advance!
