How do airlines manage fuel price risk given the time lag between ticket sales and flights?

I’m curious about the operational side of fuel price exposure for airlines. When an airline sells a ticket months in advance, they’re effectively committing to a future flight without knowing what fuel will cost at the time of operation. Do they hedge extensively through futures and derivatives to lock in prices for anticipated fuel needs, or do they rely more on dynamic pricing to adjust fares as fuel prices move, I understand that jet fuel markets aren’t as liquid as crude oil markets, so I’m also wondering how that affects hedging strategies.

For airlines with different business models, like low-cost carriers versus legacy airlines, do their approaches to managing this risk differ significantly in practice?
