Independence Day weekend is expected to be the second busiest for travel since 2000, with flight delays, cancelations and staffing woes.
Why it matters: It's a sign that the summer of "revenge travel" is upon us, with Americans splurging on travel and enduring delays to make up for pandemic-related cancellations.
The big picture: Airlines from coast to coast have been bracing for "operational challenges" this weekend, with some even encouraging customers to rebook their plans for another weekend.
Zoom in: Philadelphia International Airport this week saw roughly 180 delayed flights and 27 cancellations on one day alone.
On any given day in recent weeks, Seattle-Tacoma International Airport has experienced a dozen or more delayed flights and a handful of cancellations, per the flight tracking website flightaware.com.
