Whats the normal stockpile? Isn't the entire US national strategic oil reserve only enough for like 1 month of US usage? 6 weeks of stockpile does not seem like a crazy number to me.
It fluctuates wildly based on the whims of who is in charge, but the last alterations of the rules indicates 90 days of US imports (doesn't specify usage).
"International obligations
As a member of the International Energy Agency (IEA), the United States must stock an amount of petroleum equivalent to at least 90 days of U.S. imports. The SPR contained an equivalent to 141 days of imports as of September 2016. The United States is also obligated to contribute 43.9% of petroleum in any IEA-coordinated release."
The strategic oil reserve is crude oil. It has to be sent to a refinery before it can be made into things like jet fuel. Some refined products don't have a long shelf-life so it is only manufactured to meet demand.
That "6 weeks" probably reflects oil that is already in the refinery supply chain and is therefore deliverable over the next several weeks. The issue is that the top of that funnel is not being refilled.
The US is an exporter of jet fuel but places like Europe and Asia or more exposed to bubbles in the supply chain.
United has already cut flights by 5%, the article says KLM is cutting ~1% of their flights, both citing fuel shortages. If giant companies on opposite sides of the Atlantic, are saying this is an issue, it's probably worth taking their word for it
KLM is citing fuel price, not shortage. They’re cutting under utilized flights which they cannot perform profitably at current prices. They’ve explicitly said it’s not because of a shortage.
A shortage can also be physical. The fuel you already bought (and possibly paid for) cannot be delivered. Maybe the actual delivery is the issue. Maybe a government confiscated it for other uses. Or maybe the fuel doesn't exist at all, because the refinery didn't have the oil to produce it.
For jet fuel? The article does not say, but if they are correct in predicting shortages in six weeks, then the stockpile (if any) is not terribly large.

In any case, whatever it is, crude oil is not yet jet fuel. The crude has to be refined to output jet fuel (and other oil byproducts), and some amount of gulf refinery capacity is also offline due to one or both of damage or inability to export via sea through the strait.
Assuming that this is in any shape or form correct, why hasn't rationing started? Six weeks at normal flight capacity is an insane amount of fuel, rationing it out for transport of critical goods and travel, will stretch it for years. If the plan is to just burn through the existing stock I'd argue that someone is acting incredibly irresponsibly.
From what perspective? The individual flight operators maximize their earnings by running as many flights as they can, and charging as much as they can. Individuals who need transportation also maximize their utility from the same thing.
Perhaps rationing has already started? My coworker and his family received notice today that their flight to France was cancel. Part of the message said:
"The disruption is caused by extraordinary surge in oil prices followed by unpredictable fuel supply shortage constraints across the aviation industry outside our control. As a result, we are unable to operate this route in a responsible and sustainable manner."
It's not like Europe is actually running out of fuel. 20% of the world's oil passes through the strait of Hormuz, but closer to 10% of Europe's oil imports. They get a lot of their oil from Norway, the US, Libya, Kazakhstan, etc.
Losing that much oil hurts. But it's entirely in the realm of what market forces can deal with. As storages empty prices rise, which lowers demand. There's already reports of multiple airlines suspending some of their flights because they aren't economically viable right now
Rationing in Europe is hard because thanks to free travel it has to be done in all of Europe all at once otherwise people are just gonna go and shop where it's more available, causing problems for neighboring countries, and doing anything at a EU level is incredibly slow and full of bureaucratic rigmarole.
The EU is by its construction a trade harmonization organization, it's not built for acting quickly and dealing with crises.
More than 6 weeks of refined product also tends to be hard to maintain - moisture, bacterial/fungal growths (really - especially in kerosene derived products), oxidation/gumming (usually more of a problem in lighter fractions like gasoline).
Even 6 month type stockpiles usually take special regular maintenance procedures.
The distribution of jet fuel is not uniform. Some regions are unlikely to experience shortages while others are already rationing. Global supply chains aren't perfectly elastic, shortages are a local phenomenon. Rationing in the US, for example, wouldn't make sense because physical shortages are unlikely to exist there; the US exports jet fuel and has a completely domestic supply chain. Market prices will increase but the product will physically be there.
An airline can only schedule flights if fuel is guaranteed to be available at both ends. If they fly their plane to a part of the world experiencing severe shortages, the plane may become stranded there because there isn't fuel to fly it back.
Note that this isn't six weeks of reserve, it's an estimated six weeks of draw-down given what they're still receiving from other sources combined with (I suspect) both known fuel in transit and a reserve that wouldn't last nearly as long as six weeks if it were all they had.
If they can increase supply or reduce demand, the reserve will take longer to draw down.

Every business is prioritizing stocking up on goods they need already. They need transport to do that.

Rationing causes serious problems. A warning in advance gives people and powers time to turn things around before rationing becomes necessary.
