Every figure traces to a numbered source

Figures were gathered over the two days after the outage

Collection ran on 14 and 15 November 2026, Sydney time. That is Friday evening to Saturday evening in the eastern United States.

Official pages came first: airline travel alerts and newsrooms, FAA advisories, regulator notices, airport statements and insurers' policy wordings. News coverage filled the gaps where an official page could not be read or said nothing.

Policy wordings for non-English markets were read in the original language.

Each figure carries one of three source checks

• Checked at sourceThe original page was read and the figure is on it.
• Reported elsewhereThe figure was reported by another outlet, or the original page blocked reading. Check it against the original before reusing it.
• Not confirmedSources conflict, or the figure could not be confirmed. Conflicting figures are shown side by side.

Flight counts are snapshots with a time attached

Cancellation and delay counts changed through each day, so every count is recorded with the time it was taken. Two counts for the same day can both be right.

Tracker figures such as FlightAware's were read through the news outlets that published them. Sunday 15 November figures are cancellations logged in advance; final Sunday counts did not exist at collection.

Insurance outcomes come from policy wording

"Pays", "Depends" and "Does not pay" describe how a product's published wording treats a delay caused by an air traffic control failure. They are readings of documents. No insurer had published a position on this event when the data was collected, and no claims data exists yet.

Waiting periods and benefit caps are quoted in the currency of the policy.

Currencies convert at central bank rates for 13 November 2026

When a home country is selected, US-dollar costs are also shown in that country's currency. The rate is the central bank reference rate for the day of the outage. Where a central bank had not published for that date, the rate is derived from European Central Bank reference rates and labelled as derived.

Insurance benefits are never converted.

Search interest is an index, never a count of searches

Google Trends reports relative interest from 0 to 100 inside each request. Terms were compared through a shared term so they sit on one scale, where "flight cancelled" at its busiest hour equals 100. The largest terms needed a second step and carry an error of 20% or more.

The window runs from 7 November to 6pm Eastern on Saturday 14 November. State and metro figures cover all seven days.

Hotel and car hire prices have no dataset behind them

• No hotel, rental or booking company had published rate or occupancy data for this event. Those sections rest on company statements and individual prices reported by news outlets.
• Past-event counts by year come from news coverage and should be read as minimums.
• Visitor numbers by country are 2025 arrivals from the US National Travel and Tourism Office. The share who take a US domestic flight is published only for overseas visitors as a group.
• The page gives general information. It does not take personal circumstances into account.

Jeremy Cabral built this site after his own flight was cancelled

Jeremy Cabral is a Sydney-based growth advisor who has raised money for homelessness for 11 years. In November 2026 he queued for four nights to be first in line for the iPhone Duo at the Apple Store in Sydney, then gave the phone away to raise money for We Are Mobilise, and gave free business help to more than 100 businesses that week. He built this research site after his own flight was cancelled two days before the FAA ground stop.

This site sells nothing, carries no advertising and takes no money from airlines, insurers or card issuers.
