A) Etihad availability seemingly has zero connection to availability displayed to partners (which is logical, in a way, being as they're not a partner).
B) Being as it has nothing to do with partner availability, business does exist, even though there's nothing in I class.
I tried to press the agents to tell me what class the availability was in, but they didn't know.
C) They refused to put awards on hold.
D) They claimed to be unable to book BRU-TLV (or any SN flight with a four digit flight number).
E) The agent I spoke to was willing to book a mixed cabin redemption. It sounded like the system didn't give them costs; they had to manually input what to charge you.
