745 or 915 am from Cuzco to Lima when next flight leaves Lima at midnight?
 

I have a flight leaving from Lima to Houston around midnight, should I take the Cuzco flight at 745 am or 915 am? I've heard earlier is better due to possible delays. But that would be a pretty long layover. Should I use points and relax at Radisson Miraflores for a bit? Or just use left luggage at Lima airport and have a day tour?

Hi 715 or 945 probably doesn't matter. I dislike getting up too early. Actually, the 945 because by then any fog that may be will be burnt off. 715 will give you more time in Lima. Anyway May isn't bad for weather and there are tons of flights all day to LIM.

In Lima, for sure go and see something, lots of options.
