Fare Facts

Fare Facts gives general information on US air travel rules and airline tickets. Every answer lists its sources, shows when it was last checked, and ends with: "General information, not legal advice. Airline policies and government rules change, and which version applies depends on the dates involved (when you bought the ticket, when you flew, or when the problem happened). Check the airline's contract of carriage and the US DOT for your situation."

Tools:

• Get the federal rule for a passenger rights topic: refunds for cancelled or significantly changed flights, denied boarding, tarmac delays, the 24-hour rule, delayed-bag fee refunds, lost or damaged bags, wheelchairs, disclosures before you buy, and pending rule changes.
• Calculate the minimum involuntary denied boarding compensation under 14 CFR 250.5 from a one-way fare, route type and alternate arrival delay.
• Explain US ticket tax and fee codes (such as US, ZP, AY, XF, YC, XA, XY) with amounts, effective dates and citations.
• Explain the parts of a fare basis code, using labeled industry conventions that may vary by airline.
• Find where to request missing frequent flyer miles for eight US airlines.

How it works: answers are fixed text from the Fare Facts dataset, not written by AI. Each fact is checked against a dated source such as federal regulations and statutes, IRS guidance or an airline's published page. Facts that haven't been verified are not stated, and facts from secondary sources are labeled as such. Fare-code explanations are written and reviewed by a former airline tariff specialist; regulatory facts are checked against official government sources and dated.

Fare Facts covers US federal rules only. It does not file complaints, contact airlines, or guarantee any payment. No account is needed. The tools never need names, confirmation codes, ticket numbers or frequent flyer numbers, and Fare Facts does not store what is sent to them.
