Source Policy

The source hierarchy TripPlanWise uses for travel facts that can change before a trip.

Last reviewed:

Source hierarchy

Official government, regulator, airport, public-transport, public-health, and tourism sources are preferred for rules and public information. The provider responsible for a commercial service is preferred for its current price, schedule, allowance, availability, and terms. Maps, reviews, and independent guides can add context but do not override an official rule or provider contract.

Airline baggage

Official operating-airline baggage pages, booking disclosures, and baggage calculators are preferred. The marketing carrier, operating carrier, fare, cabin, route, status, and special-item policy can change the answer, so a static summary never guarantees airport acceptance or a fee.

Flight rights

Official regulators and legislation portals are preferred, including relevant EU, UK, U.S., Canadian, or local authorities. Airline pages can explain claim channels and current procedures. TripPlanWise organizes evidence and questions but does not decide legal eligibility or claim outcomes.

Currency and travel money

Currency tools identify the reference-rate provider when conversion is available. Reference rates are planning inputs, not guaranteed transaction rates. Travelers should verify card markups, ATM charges, cash-exchange spreads, taxes, and provider fees with the institution completing the transaction.

eSIM and connectivity

Device manufacturers and mobile or eSIM providers are preferred for compatibility, lock status, included countries, network access, hotspot limits, speed, fair-use terms, activation, and support. TripPlanWise does not publish paid provider rankings as objective fact.

Destination planning

Official tourism, airport, transport, weather, immigration, and attraction sources are used where possible. Neighborhood guides, maps, and traveler reports can help with context, but current entry, safety, opening, ticket, and transport information must be checked before booking.

AI-generated destination visuals

Some destination visuals are original AI-generated illustrations created for TripPlanWise. They are clearly disclosed, used to represent the general character of a destination, and are not documentary photographs or evidence of current weather, crowds, construction, prices, access, or attraction conditions. Travel facts are checked separately under this source policy, and travelers should use official sources for current conditions before booking.

Volatile facts and corrections

Rules, prices, schedules, weather, event policies, baggage allowances, and service coverage can change after review. Readers should re-check important facts near booking and departure.
