United Airlines international phone number: which one to call

United's reservations directory lists English on 1-800-864-8331, 24 hours daily, in a table headed "Hours available (CT)". Right above it United writes: "These numbers should be used when calling from the U.S. and Canada. Those calling from other countries should use one of our international reservation numbers."

So on your own phone abroad, the 800 number may not connect. Our test call on 20 October 2026 went out through Browzerphone's US phone provider from a US (+1) number, so it connected as a call within the US. It reached a voice system that asks you to say in a few words why you are calling; when we said nothing, it asked twice more and ended the call after about 1 minute 14 seconds.

United also says: "To book with an agent, there's a $25 fee by phone and $50 at the airport."

For calls from outside the US, United lists reservations numbers by country and notes: "International calling fees may apply." The page names no time zone for these hours, so they are presumably local time:

In our test on 20 October 2026, made through Browzerphone from a US (+1) number, the UK line played a short menu (1 reservations, 2 MileagePlus, 3 anything else) and a recording notice, and a person answered after about 46 seconds without us pressing anything. The German line greeted us in German, offered 1 for English and 2 for German, asked us to press 1 if we agree to the call being recorded, read the same three-option menu in English, and a person answered after about 67 seconds. We did not call the French number.

For the UK, United also prints 0845-607-6760 next to the London number, and 0845-607-0777 for United Polaris customers only. We did not test them.

United's list of international reservations numbers has no entry for Poland. United does not say which number callers in Poland should use; its chat on united.com is, by United's own words, available 24 hours a day.

For lost or delayed bags, United lists its Baggage Recovery Center on 1-800-335-2247, toll-free from the US and Canada and in English and Spanish only, and for Asia Pacific and Europe "Country access code + 800-33-55-2247". We did not test these.

Browzerphone calls phone numbers from a browser tab, with no SIM card and nothing to install, and shows the price per minute before you call; the rates page lists it for the UK, Germany, France and the United States. Our test calls went out through Browzerphone's US phone provider from a US (+1) number, which is why United's 800 number connected in our test. The keypad for the menus is in the same tab.

Without credit, Browzerphone only allows a free trial call, and it ends after one minute. On the German line a person answered only after about 67 seconds in our test, so top up first.
