🛫 Understanding Multi-City Itineraries
A “multi-city” or “open-jaw” itinerary typically includes:
More than two flight segments (e.g. A → B → C → D).
Different arrival and departure airports.
Mix of domestic and international flights.
Stopovers or complex routing.
Because fares are calculated for the full itinerary, changing or canceling one leg can impact the rest.
⚠️ Why Online Changes Often Fail for Multi-City Tickets
Fare recalculation required — online system may block it.
Different fare classes across segments (e.g. Economy + Business + Award).
Partner airlines or codeshares complicate reissue.
Mixed rules for domestic vs international legs.
Third-party booking origins.
In many cases, online “Change” or “Cancel” buttons are greyed out or return errors — a sign you need manual support.
🎯 How to Change or Cancel a Multi-City Itinerary (2025 Steps)
✅ Step 1: Review Your Ticket Fare Class & Conditions
Identify fare class of each segment (Economy, Premium, Business, Award).
Confirm whether tickets are refundable/ changeable.
✅ Step 2: Decide What You Need — Change or Cancel?
Partial change: altering one or two legs, keeping the rest.
Full cancellation: cancel entire journey, request refund or credit.
Reschedule: change dates or times of flights across segments.
✅ Step 3: Call United Immediately: +1 (844) 817-0364
Explain your itinerary and changes. Ask the agent to:
Reprice all segments properly.
Retain fare credit for unused segments.
Reissue booking — ensure ticket remains valid.
Confirm new booking number, seats, baggage, and itinerary.
Online tools cannot handle this complexity reliably — manual agent intervention is best.
🔄 Common Multi-City Change / Cancellation Scenarios & What You Should Know
Situation What to Do / Expect
Change single segment date/time Agent recalculates fare; may pay difference or get credit
Cancel one leg (e.g. return flight) Remaining segments may stay valid — agent must reissue
Convert multi-city to simpler itinerary Possible, but needs full reissue and fare recalculation
Mixed cabin / fare classes Agent checks fare rules to avoid invalid fare combos
Booking via travel agency / third-party Agent can liaise with agency or request override
International + domestic end-to-end trip Fare and ticket validity varies — manual reissue essential
💡 Pro Tips for Multi-City Rebooking/Cancellations
Save original booking confirmation & fare rules.
Avoid Basic Economy or heavily restricted fares for multi-city travel.
If you anticipate changes, book “flexible” fare classes (Standard Economy, Premium, Business).
Always call — rarely can online tools manage multi-city properly.
Confirm new ticket number and entire updated itinerary before leaving the call.
