Expedia says United Airlines won't refund just the part of the flight it canceled.

Can United Airlines cancel my flight and refuse to give me a refund?

United Airlines just canceled Pamela Money’s return flight from a remote area of Canada, so where’s her refund?

She says an Expedia agent cheerfully informed her that United Airlines would give her a voucher instead of cash. But that doesn’t sit right with this passenger, and she’s hoping we can get her money back.

What’s really going on here?
