Multiple web search results confirm that California's summer travel season faces uncertainty due to global oil issues and jet fuel reserves. One source mentions the 'global oil crunch,' another notes 'shrinking jet fuel reserves,' and a third mentions 'sustained higher prices and airline schedule' issues, indicating a consensus on the threat.

Multiple web search results corroborate that California's jet fuel supply has dropped to low levels, specifically mentioning 'two-year lows' or 'lowest level since 2023,' confirming the core assertion.

One web search result directly states that California’s in-state oil production peaked around 1985 at approximately 424 million barrels annually. While Wikipedia provided general state information, the specific historical data point is corroborated by the web search citing the peak year and volume.

This claim is directly linked to the evidence for Claim 2. The web search result containing the peak data also states that production has 'experienced a long-term, steady decline, with current production falling significantly,' corroborating the decline aspect, although the specific figure of '285,000 barrels per day' is not independently verified by the provided search results.

Two separate web search results confirm the impact of refinery shutdowns by Phillips 66 and Valero, stating that the closures 'wiped out roughly 17% to 20% of California’s gasoline production capacity.'

Multiple web search results independently report that Air Canada stated that jet fuel prices have doubled since the start of the Iran conflict, leading to unprofitable routes.

Two web search results confirm the specific suspension dates and routes: Air Canada suspending flights from Toronto and Montreal to JFK between June 1 and October 25, 2026.
