What?
Airline can negotiate fixed terms with fuel suppliers so they are not affected by price fluctuations. When fuel prices increase, an airline has a competitive advantage. If they fall, the opposite is the case.
Conditions of fuel hedging contracts depend on their duration and possibly market outlook. A broker-like system similar to the one suggested for the aircraft market might allow players to pick between different options, with some options only available to new players.
Why?
Albeit not a crucial feature, this has been requested many times in the past and makes sense from a “reality stand-point”.
When?
TBD
