Agreed. Right now if you have two or more bases the breakdown for each is just a guestimate.
I also find the contracts on offer at various bases to be rather random. How are fuel companies competing with one another when one offers, for instance, 4% for 7 mil for two years and other 5% for 3.5 mil for two years? I realize there is probably some kind of randomizing algorithm at work, but right now decision to go with a contract relies too much on timing, and frankly, luck. It would be better (and more challenging), in my opinion, if the competing contracts were more structured around short term / long term advantages: one company offers a better deal, but only for the short term; another less good in the short term, but obviously better long term. Then difficult decisions would have to be made by airlines. That may, in fact, have been what Sami intended in setting up the system, but right I haven't seen it work out that way.
