I'm taking an important exam that is only offered in a limited number of cities once a year (the JLPT, for the curious) this December 2. When I have taken other levels of the exam in years past, I have always done so in Chicago, but have had narrow misses with ORD weather and missing the exam both times.

This year, for various reasons, I need to make absolutely sure that I actually take the test. In addition, while in the past I have always allowed myself a buffer day (leaving myself an extra day before I need to be there), that isn't going to be an option this time.

I'm in CLE, and I need to get to leave in the afternoon/evening on Dec 1 to arrive in either ATL, DCA, HNL, SFO, LAX, or NYC in time for an exam in the early afternoon on Dec 2. Using UA or US, if possible.

I don't have nearly as much experience with this sort of thing as many on here, so I figure I would ask for some advice for what the best way to do this is without getting grounded due to bad weather.

Thanks in advance!
