I have a late flight out of HKG next Tuesday night, when it looks like Typhoon Ragasa will be near to HK. I'd really like to not get stuck in HK for any extra time, so I'm wondering if it would be worth calling Cathay to see if I can change my flight to be a day earlier without a fee, even though there's no waiver in place yet. Is that something they have the flexibility to do, or should I not even bother? I know I can also log in online and change my flight for a fee there, but if there's a chance they'll do it without a fee, I'll get over anxiousness and call.
