Holiday weekends tend to make both departure and arrival windows slower than the raw route time suggests.
Time zone

Origin and destination are on the same clock, so arrival timing is easier to judge at a glance.
Temperature spread
Very similar conditions
Both ends of the route are sitting at about the same temperature right now.
