I always like to have the longer nonstop flights on TATL/TPAC in order to get dinner and a good night's sleep before it's time to wake up for breakfast and landing in business class. In addition, I hate arriving in Europe at the crack of dawn when you won't have access to your hotel room for many, many hours (and I'm usually too cheap to book the extra night to guarantee use of the room for just a couple extra hours).
