If anybody is considering the day flight option, AA do day flights from Boston, New York & Chicago. BA do Boston & New York. There may be others that I'm not aware of.

I've done all the AA flights and Boston is my preferred option because it's the shortest and you can get in before 8 o'clock sometimes. The Chicago flight gets in around 10.30 pm and is a much longer flight although still better in my book than the equivalent night flights.
