Why the language of booking matters
Travel booking platforms and insurance providers use industry shorthand that, if misread, can mean paying more than expected, losing a refund, or assuming coverage that does not exist. This glossary covers the terms you are most likely to encounter when comparing flights, hotels, and travel protection, with plain definitions and context for each one.
For a broader look at how these terms interact in practice, see common booking errors to avoid.
| CFAR reimbursement range | Typically 50 to 75 percent of non-refundable costs (General industry range; verify with individual policy) |
| CFAR purchase window | Often within 14 to 21 days of initial trip deposit (Varies by insurer; confirm before purchasing) |
| Fare classes per cabin | Economy can have 10 or more letter codes (Varies by airline) |
| Pre-existing waiver deadline | Commonly 10 to 21 days after first deposit (Varies by policy; check the fine print) |
Booking and fare terms
Fare class (also called booking class) is a letter code airlines use internally to group seats by price and rules. Two passengers sitting in the same cabin may hold different fare classes, which determines whether their ticket is refundable, changeable, or eligible for upgrades. Economy alone can have a dozen fare classes.
Base fare vs. total fare: The base fare is the airline's charge for the seat only. The total fare adds government taxes, airport fees, and carrier surcharges. Advertised prices are sometimes base fare only; always confirm the total before comparing options.
Codeshare flight: A flight marketed and sold by one airline but operated by a different carrier. The ticket number, check-in process, and baggage rules may follow the operating airline rather than the one you booked with. Confirm which airline operates the flight when reviewing policies.
GDS (Global Distribution System): A network that connects airlines, hotels, and car rental companies to travel agents and online booking platforms. Prices can vary slightly across GDS networks, which is one reason the same seat may show different fares on different sites.
Non-refundable ticket: A ticket where the airline will not return the base fare if you cancel. Many non-refundable tickets still allow changes for a fee, or issue a travel credit rather than a cash refund. Read the fare rules, not just the label.
Open-jaw itinerary: A trip where you fly into one city and out of another, without a connecting return to the origin. For example, flying into Chicago and departing from Milwaukee. Open-jaw bookings can sometimes reduce cost compared to a standard round trip.
When weighing whether to bundle or book components separately, the trade-offs between package deals and separate bookings article covers how these fare structures affect each approach.
Travel insurance terms
Cancel for Any Reason (CFAR): An optional add-on to a travel insurance policy that allows cancellation for reasons not listed in the standard policy, typically reimbursing 50 to 75 percent of the prepaid, non-refundable trip cost. CFAR coverage usually must be purchased within a short window after the initial trip deposit and has its own conditions. It is general insurance information, not advice tailored to your situation; verify terms with the insurer directly.
Cancel for Covered Reasons (CFCR): The standard cancellation benefit in most travel insurance policies. Covered reasons are specific and listed in the policy document, commonly including sudden illness, injury, jury duty, or natural disaster at the destination. If your reason is not on the list, the claim may be denied.
Exclusion: A situation, condition, or event the policy does not cover. Common exclusions include pre-existing medical conditions (unless a waiver applies), extreme sports, and events that were already foreseeable when you purchased the policy. Reading the exclusions section carefully matters more than reading the benefits summary.
Pre-existing condition waiver: An optional provision, or sometimes a standard feature with purchase timing requirements, that removes the exclusion for pre-existing medical conditions. Eligibility usually depends on purchasing the policy within a defined number of days after the first trip deposit. Older travelers face particular complexity here; coverage gaps that affect senior travelers explains how age and health history interact with policy terms.
Medical evacuation benefit: Covers the cost of emergency transportation to an adequate medical facility if local care is insufficient. This benefit is separate from medical expense coverage. Transportation costs can be substantial for international travel, so the coverage limit matters.
Trip interruption vs. trip cancellation: Cancellation coverage applies when you cancel before departure. Interruption coverage applies when a covered event forces you to cut a trip short after it has begun. Both have their own benefit limits and covered reasons.
Insurance terminology overlaps with broader financial vocabulary. The plain-language finance glossary covers related terms like deductible and premium in a general context.
