Summer fares: March spike
U.S. airfares rose in March by roughly 2.7% month‑over‑month and were up about 14.9% versus March 2025, a trend analysts link to higher jet‑fuel and geopolitical uncertainty. ( ). Carriers and advisers are urging earlier bookings and refundable tickets as the summer window tightens. (usatoday.com).
U.S. airline fares jumped again in March, adding to the cost pressure facing travelers who are booking summer trips now. (bls.gov) The Bureau of Labor Statistics said the airline fares index rose 2.7 percent in March after a 1.4 percent increase in February. Over the 12 months through March, airline fares were up 14.9 percent. (bls.gov) March’s broader inflation report showed why travel costs are under strain: the energy index rose 10.9 percent in the month, and gasoline prices jumped 21.2 percent. Jet fuel is a separate market, but airlines buy a fuel product that usually gets more expensive when oil markets tighten. (bls.gov, iata.org) The International Air Transport Association said last week’s global average jet fuel price rose 7.1 percent from the prior week to $209 a barrel. On March 6, the group said the Middle East conflict that escalated on February 28 had disrupted energy flows and pushed jet fuel premiums higher. (iata.org, iata.org) That squeeze is landing just as summer booking season enters its final stretch. USA Today reported on April 12 that airlines had not yet made major summer schedule cuts, but travel advisers were urging customers to book earlier and favor refundable tickets if prices or plans change. (usatoday.com) The fuel risk is not only the price of crude oil. The International Air Transport Association said tanker traffic through the Strait of Hormuz had collapsed by 70 percent to 80 percent, while war-risk insurance and longer shipping routes were raising delivery costs for refined products such as jet fuel. (iata.org) Airlines do not automatically pass every fuel increase straight to passengers, because fares also depend on competition, demand, and how much fuel a carrier hedged in advance. But the trade group said aviation cannot substitute away from jet fuel at scale, which leaves carriers exposed when supply tightens quickly. (iata.org, iata.org) For travelers, the March data means the cheapest summer window is getting narrower, not wider. The next federal inflation report arrives on May 12, when April airfare data will show whether the March spike was a one-month jump or the start of a pricier summer.
