I'm curious about why they chose not to cancel those remaining 30 flights, and also who it was that's striking specifically (pilots, ground crew, etc). As a former customer service agent, the mess of rebooking people would be so great I would almost rather suck up my grievances with the employer than deal with that (but I really don't know the specifics of what they're dealing with, and who knows if they add more flights the next day to make up for it).
