To be honest, no one knows. Logic is not one of the factors in airfare pricing it seems. That said:
Yes, fuel prices have increased, but airlines contract fuel way out (with contingencies) and while oil prices are up, that may or may not directly affect aviation fuel prices and contracts.
The buzz seems to be that people are rethinking travel, lower volumes may soften prices, offsetting fuel increases.
This, whatever it is, may be over with next week, go on for months, or unrest and no "war" may disrupt oil supplies for years. (Iran has indicated that it can disrupt flow at any time, and it can, through mines or attacks) Then add in waffling on sanctions against Russian oil, unknowns about Venezuelan oil, impact on prices due to the losses that the Gulf states have suffered, the variables can make an analysts head ache.
But, seeing that October is only 7 months out, why not buy? I typically buy about 6 months out, if the price looks good, go for it, don't fret on whether it will go up or down. Many airlines now allow you to rebook at no cost, so if I see a lower fare (on Delta) I rebook and take the savings as a credit.
