Interesting. I always wondered why the fare for 2 bags on their website is so much more than via the GDS. Unlike most airlines where even if they don't charge GDS fees, they will be equal or less on their own website (besides AZ who charges a fee for booking online)
Interesting anecdote regarding AZ.
I just booked a ticket for someone TLV-JFK-TLV on AZ and didn't realize on the booking page that fare said it doesn't include checked luggage. After printing the confirmation, I saw that no checked luggage is included, so I called AZ to ask for cancellation. They said they couldn't give a full refund because flight is less than a week away, but then they told me that 1 free bag is included in the fare, and sent me an email confirming that.
