How much have airfares risen with high jet fuel costs?

Airfares have risen amid high jet fuel costs, according to data cited from flight search engine Skiplagged. For popular domestic routes, ticket prices increased 35% this summer compared with last year, ending three years of declines. International routes rose by about 15%, despite analysts noting that flights abroad are generally longer and use more jet fuel, which nearly doubled in price since the start of the Iran war. The article explains that international price spikes may have been muted by lower demand to the U.S. and the difficulty airlines face in adjusting routes quickly, while domestic markets can see higher prices when airlines reduce capacity during weak demand. More than half of domestic flights in the sample saw at least a 25% increase. Airlines have also shifted costs to customers through higher fares and bag fees. Southwest CEO Bob Jordan said the carrier has issued seven fare increases since February without a demand drop.
