May U.S. domestic air travel demand, as measured in revenue passenger kilometers, declined for the fourth month in a row, according to the International Air Transport Association. U.S. traffic decreased 1.7 percent year over year, following declines of 4.2 percent in February, 1.7 percent in March and 0.5 percent in April.
Economic uncertainty and a reduction in government travel contributed to the contraction, according to IATA. The May U.S. passenger load factor dropped 3.1 percentage points year over year to 83 percent, while capacity, measured in available seat kilometers, increased 2 percent compared with May 2024.
Total May global demand increased 5 percent year over year, as did capacity. The May load factor was down 0.1 percentage point to 83.4 percent versus May 2024.
May international demand rose 6.7 percent year over year, while capacity increased 6.4 percent. Load factor increased 0.2 percentage points to 83.2 percent, the highest on record for May international flights, according to IATA. Domestic demand was up 2.1 percent versus May 2024, while capacity increased 2.8 percent during the period. The overall domestic load factor slipped 0.5 percentage points to 83.7 percent.
“Air travel demand growth was uneven in May,” IATA director general Willie Walsh said in a statement. “Severe disruptions in the Middle East in late June remind us that geopolitical instability remains a challenge in some regions as airlines maintain safe operations with minimal passenger inconvenience. The impact of such instability on oil prices—which remained low throughout May—is also a critical factor to monitor. Importantly, consumer confidence appears to be strong with forward bookings for the peak Northern summer travel season, giving good reason for optimism.”
