I'm flying the day after tomorrow (March 14th). It seems there's no cancellations as of yet, am I wrong?
I changed the flights for BTV-EWR / EWR-IAD / IAD-PEK to be extra careful.
If BTV-EWR (first flight out of BTV) in impacted, I can change to BTV-ORD or BTV-IAD and still get on a flight to PEK the same day.
If EWR-IAD is impacted, I can get on the EWR-PEK, or connect through ORD, or even try to go to SFO/LAX for other flights.
I could fly out of YUL (where I'm based), but the agents cannot rebook me (yet) on YUL-IAD/EWR/ORD, as I need to keep same O&D.
Also, I think YUL might be impacted as well by the snowstorm, but at least here we're used to it!
just monitor your flight status frequently tomorrow. If your first flight to EWR is cancelled for March 14, you will have a strong case to change your originating city to YUL. This will help UA out and agent should have no problem to make the change for you.
good luck.
