What should I check before booking an international flight with United Airlines?

Before booking an international itinerary with United Airlines, list every airport and country in travel order, including connections. Then check the rules that apply to the traveler's citizenship, passport or other document, residence when relevant, trip purpose, dates and minor status. Confirm each segment's operating airline, whether all segments share one ticket, and the current destination and transit requirements with the responsible government authorities. For United Airlines specifically: United's document workflow is itinerary-specific and uses the confirmation or eTicket context; generic brand guidance cannot determine a traveler's eligibility.

  • United can organize travel-document tasks, but the applicable government authority remains the source for entry or transit permission.

Important exceptions

  • The result may differ depending on direct vs connecting.
  • The result may differ depending on united vs partner operator.
  • The result may differ depending on destination entry vs transit.
  • The result may differ depending on single ticket vs separate tickets.

    Confirm whether the itinerary is one protected ticket or separate tickets and whether baggage is checked through.

    Identify the marketing and operating airline for every segment and review the airline's itinerary-specific document workflow.
