I was planning on booking this on a crazy ATH-WAW-YYZ-BOS itinerary using United miles for biz class.
So 55min is not legal? Does this mean United won't let me book this? (off topic, sorry)
Second, what is the later AC flight to BOS? The latest I see is the 6:15pm on the United.com award booking site.
