Editorial author, Your Flight Help

John Robert writes and maintains the guides on Your Flight Help, following the site’s editorial methodology: plain explanations, official sources for anything that changes, and clear lines between samples, reservations and tickets.
Every guide follows our editorial methodology. Requirements that change, such as visa and entry rules, are checked against official sources and dated. Where a guide shows a “facts reviewed” date, that’s when those facts were last checked.
