Well, you have to adjust your prices accordingly. And demand changes a lot in troubled times, so there are probably routes to change.
My tickets prices from London City to Rotterdam are far higher than from Corfu to Skopje, despite the distance being inferior. Richer people can afford bigger prices. The difference is especially steep when your RI is low and you're flying high-density seats, but it's even present with 90 RI and standard seats.
In case of big change(good or bad, I had an opponent in Warsaw & Hamburg collapsing recently), check all your routes, increase prices of everything above 90% LF, and be prepared to decrease prices for some lines under 60% LF(though it's not automatic here. For some specific short lines with a lot of opposition, a price war can be even worse than lower LF - and is not gonna hurt your opponents much anyways).
