From NPR.

As the war in Iran entered its third week and the price of oil reached nearly $105 a barrel Monday, airlines are starting to add fuel surcharges to ticket prices.

Jet fuel prices are up over 75% since last year — a huge spike in one of air carriers’ biggest expenses. Sean Cudahy, of The Points Guy, says their customers will eventually absorb some of that increase: "It’s just a matter of when and how significant." He recommends locking in an airfare now.

Gas prices also continue to surge. According to AAA, they’re now an average of $3.72/gallon — nearly 80 cents higher than a month ago. Diesel prices are also up more than $1.30 over the past month. If those prices hold, they could drive up transportation costs for anything that travels by truck or train.

The Trump administration insists the spike will be short-lived.
