How can I modify an existing booking with United Airlines?

First identify who issued and controls the ticket, then retrieve the exact United Airlines itinerary through the Canada-English My trips path. Compare the original and requested airports, dates and segments; check whether the change is voluntary or airline-initiated, whether travel has started, the fare rules, the operating airline and the live price difference. United's FAQ confirms that a booking made elsewhere can be retrieved and saved to an account, but it does not establish that United controls every ticket change.

What this answer depends on

  • United requires the exact booking to be retrieved before showing the actions available for that itinerary.
  • United's Canada-English My trips FAQ says a reservation booked elsewhere can be saved to an account while it is being viewed; that establishes retrieval/account storage, not that United controls every ticket change.
  • Basic Economy and standard cabin tickets do not share one change rule, and live fare difference or inventory is visible only after retrieval.

Important exceptions

  • The result may differ depending on direct vs agency issued.
  • The result may differ depending on voluntary vs airline initiated.
  • The result may differ depending on basic economy vs standard.
  • The result may differ depending on before departure vs no show.
  • The result may differ depending on same route vs airport change.
  • The result may differ depending on united vs partner operator.
