Travel rules should be usable, not just searchable
PrismGist builds source-checked pre-flight travel technology tools. Our goal is to help travelers apply airport, airline, aviation-authority, and product-safety rules to an actual itinerary before they leave home. We also publish AI product guides and downloadable worksheets that help readers assess access, usage limits, evidence and subscription decisions.
How our tools work
- We begin with primary sources such as official airport, airline, regulator, and product-safety pages.
- We record when a source was checked and distinguish a published rule from our plain-language interpretation.
- For multi-airport or multi-airline trips, we compare the relevant checkpoints or operating carriers and surface the strictest applicable outcome.
- When a reliable answer is not supported by the available sources, we say so and recommend checking directly with the responsible authority.
Who maintains PrismGist
PrismGist Editorial Team is the site’s editorial byline. PrismGist uses AI assistance for research, drafting and content maintenance, and AI-generated illustrations where disclosed. That byline does not imply a named expert panel, professional credentials or firsthand product testing. Source checks, calculation tests and limitations are described in the relevant guide or tool; publication alone is not proof that every claim has been independently verified. We document material corrections when better evidence becomes available.
PrismGist is an independent information service. It is not an airport, airline, security authority, regulator, or product manufacturer, and it cannot grant approval to carry an item or board a flight. Always follow instructions from the operating carrier and officials at the checkpoint.
