Find reviewed United Airlines routes between the United States and Japan, flight numbers in both directions and official links for status, airport assistance and disruption questions.
Start with the airline’s official flight information
Search using the local departure date and UA operating flight number. Guam and Saipan dates may differ from the date in the continental United States.
This page does not submit a refund claim, retrieve a certificate or confirm live flight status. Ask the airline for the documents and case number required for your situation.

Schedule period and official checks →At the counter: replacement flight, bags and documents
Show staff your booking and ask for the replacement flight’s arrival date before accepting it. Confirm whether to collect or transfer checked baggage. For an overnight disruption, ask which hotel, meals and transport are approved before spending money.
If a bag is missing or damaged, report it before leaving the airport, keep the bag tag and obtain a reference number. Ask for the written-claim deadline; this directory has not verified a carrier-specific deadline.
For an insurance claim, request the document your insurer asks for. A screenshot alone is not an airline certificate or a guarantee of reimbursement.
Refund eligibility, supporting documents and baggage guidance →Common questions
Which United Airlines flight number should I check?
Use the operating flight number and local departure date shown on your booking. A codeshare ticket can display another airline’s marketing number. The route records below are not a live status feed.
Are check-in counters and deadlines confirmed here?
No. Terminal, assigned counter, counter opening time, check-in deadline and boarding deadline need confirmation from the operating airline and airport for your travel date. A delayed departure does not automatically extend check-in.
