I'm asking on behalf of my mom, who is supposed to fly JFK-BOS tomorrow at 2PM -- during what may be a major snowstorm. She is considering taking Amtrak to Boston.

If B6 cancels her outbound flight due to weather, does the return flight stay valid?

It would seem that the answer would be "yes" because it would not be my mom who missed her outbound flight; rather, it would be B6 that cancels the flight. So it seems that it wouldn't be right for B6 cancel her return flight. But how would B6 credit her? When a flight is canceled, I believe you have the option for a full refund. But if you take the return flight, you couldn't possibly be eligible for a full refund -- nor should you have to still pay the full fare.

Also, if she takes Amtrak but her outbound flight is not canceled, can she still save her return flight some way?

Any ideas? Thanks.
