There is no significant difference. Cruise Speeds (and Mach number limitations) can vary depending on the temperature of the air and other factors, but the actual effect on the speed of the aircraft (in cruise) is usually very small.

Technically, no. Day/night has nothing to do with it. If anything, pilots that are flying under Visual Flight Rules (VFR) might opt to fly higher than during the day to improve their odds and better avoid inadvertently flying near terrain or obstructions that are less visible.
It might be surprising to learn that turbulence is actually worse in the daytime. In the early morning and night time, wind speeds typically reduce, and thunderstorms clear up. Avoid turbulence and catch up on some sleep by choosing flights with an early morning or red-eye departure!
Landing is, without a doubt, one of the hardest things to do in aviation. Landing at night is even harder. With significantly fewer visual cues, you need to rely on your instruments and airport lighting much more during night landings.
Summer and winter are the worst seasons for turbulence. Winter has strong winds and blizzards, and summer's hot heat can create unstable air, thunderstorms, and tropical storms. That means flying during the holidays often means more turbulence than other times of the year.
Mostly (not all) pilots prefer night flying. Some pilots may love flying in the night while some may love to fly in the day. Here's how night flying is preferable to pilots: Some things are easier when it comes to night flying, some things are more difficult.
As others have mentioned, the plane can go faster, but it is less efficient, so it costs the airline more in fuel to go faster. If there is an advantage to the plane arriving a few minutes (sometimes even 30 minutes) earlier, they will authorize the pilot to pick a more favorable route and use a higher speed.
Planes have headlights so that pilots can see what is in front of them. Unfortunately, they are only effective during takeoffs and landings. Even with the slight illumination offered by the headlights, only darkness is visible when looking out the front window of a cockpit.
Pilots have a unique viewpoint while flying private or commercial aircraft. They get an unobstructed view of stunning natural sights, such as pink lakes and rectangular-shaped icebergs. Some have reported seeing UFOs, while others have flown over swirling hurricanes.
While turbulence can feel scary, airplanes are designed to withstand massive amounts of it. A plane cannot be flipped upside-down, thrown into a tailspin, or otherwise flung from the sky by even the mightiest gust or air pocket, wrote pilot Patrick Smith on his site, AskThePilot.com.
Severe turbulence can cause a plane to drop so suddenly that pilots temporarily lose control. But, again, that's not enough to crash the plane. That's not to say it's never happened. In 1966, human error and turbulence combined to bring a plane down over Mount Fuji.
Severe turbulence, he added, is “quite rare — only 0.1% of the atmosphere at 40,000 feet has severe turbulence in it, so if you're on a plane it's very unlikely that your plane will hit that 0.1%.”
The Federal Aviation Regulation (FAR) Part 91.119 indicates that, except when necessary for departure or landing, the minimum altitude over urban areas is 1,000 feet above ground level (AGL) and 500 feet AGL over rural areas.
The sensation of “dropping” comes from the retraction of the flaps and slats. The rate of climb is reduced, causing it to feel like a descent. Q: Flying and cruising altitude and landing, not a problem. Taking off, I'm not so fond of.
