This seems to be happening more and more with AC.
AC756 on 3/22. EF shows: J9 C9 D9 Z6 P6 R0 Y9 B9 M9 U9 H9 Q9 V9 W9 G9 S4 T0 L0 A0 K0
I've tried multiple points of sale (US, Canada, Europe) and asked about further advancement (SFO-YYZ vs. SFO-YYZ-AMS), and multiple AC agents all insist they see nothing below D in all cases.
Any ideas?
