This will be the busiest July 4 week for travel since at least 2019, AAA predicts.
Why it matters: The right departure time could save you hours stuck in traffic.
The big picture: The worst July 4 holiday traffic is expected to hit starting Thursday, according to INRIX, a transportation data firm that works with AAA to calculate travel times.
Yes, but: In certain metros — including Boston, Los Angeles and Philadelphia — peak congestion is expected earlier: Saturday, June 27.
State of play: To avoid the heaviest traffic, leave early in the day or consider driving on Monday or Tuesday, per INRIX.
By the numbers: AAA expects 72.2 million Americans will travel at least 50 miles for Independence Day between Saturday, June 27 and Sunday, July 5.
That's up from 71.8 million travelers last year but a smaller jump than in recent years.
Zoom in: Most July 4 travelers — 85% — are forecasted to drive this year, despite high gas prices, according to AAA.
What we're watching: For those renting cars, AAA partner Hertz also expects Thursday to be the busiest pickup day.
The top cities for advance bookings are Orlando, Denver, Boston, Los Angeles and New York City.
