FFers know a strike is part of flying any member with status huffing and puffing about leaving AC because of the strike is either blowing hot air, or not the kind of customer an airline is sad of losing.

A promo for SQX multiplier would have almost zero ROI. I suspect 25% off base fare. Which, from the flights I just booked worth about 10% of a standard Y ticket on a TATL flight.
