Depends when your flight is! It might be one that slips through the cracks and you get lucky.

Bear in mind that the airline may attempt to cancel at any time. On the Swiss RGN fares they downgraded some pax at ZRH to economy after having arrived in F on other airlines (on the same ticket).

So there's still plenty that could go wrong. But if you need to be in GYE, and accept that some of your plans may get changed (which, like those in transit at ZRH you may have little opportunity to resolve at the time), you might be willing to take the chance.
