In cooperation with AAA, S&P Global Market Intelligence (SPGMI) developed a unique methodology to forecast actual domestic travel volumes. The economic variables used to forecast travel for the current holiday are leveraged from SPGMI’s proprietary databases. These data include macroeconomic drivers such as employment, output, household net worth, asset prices including stock indices, interest rates, housing market indicators, and variables related to travel and tourism, including gasoline prices, airline travel, and hotel stays. AAA and SPGMI have quantified holiday travel volumes going back to 2000.
Historical travel volume estimates come from MMGY’s TRAVEL PERFORMANCE/MonitorSM. The PERFORMANCE/MonitorSM is a comprehensive study measuring the travel behavior of U.S. residents. MMGY contacts over 50,000 U.S. households each month to obtain detailed travel data, resulting in the unique ability to estimate visitor volume and spending, identify trends, and forecast U.S. travel behavior, all after the trips have been taken.
The travel forecast is reported in person-trips. In particular, AAA and SPGMI forecast the total U.S. holiday travel volume and expected mode of transportation. The travel forecast presented in this report was finalized the week of October 20, 2025.
Because AAA holiday forecasts focus on domestic leisure travel only, comparisons to TSA passenger screening numbers should not be made. TSA data includes all passengers traveling on both domestic and international routes, whether traveling for work or leisure. Additionally, TSA screens passengers each time they enter secured areas of the airport, therefore each one-way trip is counted as a passenger tally. AAA focuses on person-trips, which include the full round-trip travel itinerary. As a result, direct comparisons of AAA forecast volumes and daily TSA screenings represent different factors.
INRIX Methodology
INRIX blends statistically grounded models with real-world road behavior to forecast travel conditions on the most heavily traveled routes across the U.S. during peak holiday periods. INRIX’s holiday traffic forecast combines pre-selected high-impact travel routes, rich multi-source traffic data, and a statistically robust linear regression model to generate detailed, time-specific travel delay predictions. INRIX’s data sources include a wide array of vehicle-based and infrastructure-based inputs. These include connected vehicle GPS data, mobile apps and navigation services, roadside sensors and cameras, and commercial fleet telematics. With expansive coverage, high temporal resolution, and historical context, this forecasting process provides essential insights for travelers, media, and agencies alike.
Thanksgiving Holiday Travel Period
The Thanksgiving holiday travel period is defined as the seven-day period from Tuesday, November 25 to Monday, December 1, 2025. This Thanksgiving travel window was instituted starting in 2024. Historical results were calculated dating back to 2019 using the same seven-day period.
