Is US air travel demand slowing down?

IATA's September numbers came out on October 30. US domestic air travel fell 2.7 percent from a year earlier, the fifth monthly drop in a row, and the planes flew emptier. Agency-booked trips moved the other way. Here's what the data says, and what it means for an agency's fall.

How much did US air travel fall in September?

US domestic traffic, measured in revenue passenger kilometers, fell 2.7 percent from September 2025. Airlines flew 1 percent less capacity, so seats went unsold: the domestic load factor was 79.8 percent, down 1.4 points.

The trend has built through the summer. US domestic traffic fell 0.5 percent in July and 2.9 percent in August. Across all of North America, September traffic fell 1.6 percent on 1.3 percent less capacity.

Is the slowdown global?

Partly. Global demand fell 0.5 percent, the second monthly decline in a row. Most of the weakness sat in the Middle East and North America. Leave out the Middle East and global demand grew 0.3 percent.

International flying is steadier. North American carriers held their international traffic flat while cutting capacity 1.9 percent, so those flights filled better, at 84.9 percent. Transatlantic traffic slipped 0.6 percent, a smaller fall than in August. IATA says traffic fell on three of the four largest international route areas for North American carriers, with smaller drops than the month before.

The Middle East is the sharpest case. Its carriers' international demand fell 7.5 percent, and traffic between the Middle East and Asia fell 8.8 percent. If your travelers connect through Gulf hubs on long-haul trips, watch those bookings for schedule changes first.

Why are fewer people flying?

IATA suggests subdued consumer confidence may have played a role in the US. Its chief economist, Marie Owens Thomsen, expects the weakness to continue "amid geopolitical uncertainty and volatile fuel prices."

Treat the cause as an open question. IATA offers it as a likely factor, and the figures are provisional and can be revised.

Are agency bookings falling too?

Agency trips held up. ARC counted 25.7 million passenger trips sold by US agencies in September, up 2 percent. Domestic trips rose 2 percent as well. Agency sales grew 18 percent, mostly from higher fares, with the average economy fare up 21 percent.

The two counts measure different things. IATA tracks all passengers by distance flown, and ARC counts the tickets agencies sell. Read together, they suggest the agency channel, with its corporate and managed travel, is holding steadier than the wider market. We'll watch October's numbers to see whether that lasts.

What does this mean for an agency's week?

Softer demand tends to show up in the work after the booking. Here's what to plan for:

• More schedule changes. Emptier planes give airlines a reason to trim flights, and each change lands in your queue as a rebooking or a refund.
• More credits worth tracking. Fares are up, so each unused ticket carries more value. Keep every credit tied to its traveler and its expiry.
• Fare moves. Watch for sales on routes with spare seats, and reprice open bookings where the fare rules allow it.
• Steady weekly reporting. Exchanges and refunds all flow into the ARC week, so reconcile them daily.

What should agency leaders watch next?

Two monthly reports. ARC's agency sales for September came out on October 15, and IATA's traffic data on October 30, so expect October's numbers on a similar rhythm. Airline schedules give an early read too: IATA's figures show global scheduled seats up 0.6 percent for October and 1.5 percent for November.

If US domestic traffic keeps falling while agency trips grow, the gap is worth bringing to your corporate clients. It's a good moment to review their travel policy and their open credits together.
