Since 02FEB, the O fare (Promotional Business Class) has been introduced ($690), and post 04FEB, the Z fare jumps to ($1055). However, both the O and Z fares currently on sale have the note below, expiring 10FEB. Curious what will happen after that, perhaps the O will disappear and the Z will return at the previous pricing, then you can change to Z for a INR 8335/~USD 117 fee.

UNLESS OTHERWISE SPECIFIED
TICKETS MUST BE ISSUED ON/AFTER 02FEB 19 AND ON/BEFORE
10FEB 19.
