Seasonal Notes
Summer travel usually means heavier construction, hotter rest stops, and busier weekend traffic around major cities.
Winter travel shortens daylight, so a route that looks manageable on paper can feel much longer after dark.
Holiday weekends tend to make both departure and arrival windows slower than the raw route time suggests.
Time zone
Same local time
Origin and destination are on the same clock, so arrival timing is easier to judge at a glance.
Temperature spread
1 degrees cooler at arrival
A meaningful temperature swing is a good cue to rethink layers, water, and how soon you want to arrive.

Irving is a city in the Prairies and Lakes region of Texas. Part of the Dallas-Fort Worth Metroplex, Irving has experienced exponential growth over the past fifty years, and is home to a multitude of attractions of all types, from modern art to major sporting events. Founded in 1902 out of the remnants of the small community of Kit, Irving is now a bustling city of approximately 197,000 residents.
Rather like Dallas, it is divided into a highly affluent northern half and less affluent but highly diverse southern half. It is bounded to the east by the northern fork (Elm Fork) of the Trinity River and to the northwest by the sprawling D/FW International Airport.
