Hello
First post here so tell me if I violate any norms.

I am trying to book LYS-MAD-NRT-SEA-LAX-TPA-LYS, business class starting in September.

All is well (plenty of seats, valid itinerary etc), until I try to buy it. I get an error message for LYS-MAD and MAD-NRT (both Iberia flights) that says waitlists. So I tried various dates, thinking that I would pull the trigger and change it later. I have tried dates from February onwards, and get the error every time. I tried the AA chatline, but the only advice they gave me was to wait (which doesn't seem to be useful).

Any ideas?

Thanks
