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
2 degrees warmer at arrival
A meaningful temperature swing is a good cue to rethink layers, water, and how soon you want to arrive.

About the Cities
Starting in Dallas, TX
Full guide →“Big D” · Founded 1841
Dallas, with a population of more than 1.3 million residents, is the ninth largest city in the United States and the third largest in the state of Texas. It is an impressive melting pot of culture and character. Boasting high-end luxury hotels, innumerable fine dining spots, and one of the busiest airports in the world, Dallas maintains an upscale ethos reflected by an affluent population, world-class museums, and a shimmering modern skyline. Its history was marred by the infamous assassination of U.S. President John F. Kennedy, but there is more historic and contemporary heritage to be discovered in the city. As a center of the oil and cotton industries in the late 1800s and early 1900s, Dallas was a classic American boom town and remains one of the fastest growing cities in the nation.
