United Airlines passengers seeking help with a booking change, flight disruption, or luggage claim frequently turn to a search engine when they cannot navigate the United app easily. Scammers capitalise on this by running paid advertisements and maintaining fake United Airlines support websites that list fraudulent customer service phone numbers.
The fraudulent interaction follows a consistent pattern: the fake agent is helpful and knowledgeable, confirms the caller's booking details, and then introduces a fee — a 'rebooking service charge', a 'seat-change processing fee', or an 'upgrade credit' — that must be paid before the change can be made. United Airlines does have some genuine change fees, but they are charged through United's own system, not by a third party over the phone.
MileagePlus members are particularly targeted: a fake agent claims bonus miles can be purchased at a discount or that a status match requires a processing fee, harvesting both payment details and MileagePlus credentials.
How this scam works on the United Airlines brand
Fake United support sites typically appear in paid search positions for queries like 'United Airlines phone number' or 'United customer service rebook flight'. They display a prominent toll-free number and may also include a live chat widget staffed by fraudsters.
The script is designed to seem like genuine airline support: the agent asks for the flight number, booking reference, and passenger name — all of which confirm the booking is real (this data may have been obtained from a breach or the caller provides it). Then the agent introduces the fee, claiming United's system requires it for the specific type of change requested.
MileagePlus targeted calls may come as an outbound contact: a recording claiming that the member has earned a 'surprise upgrade to Premier status' and must call a number within 48 hours to activate it. The callback leads to a fake agent who collects MileagePlus login credentials and card details for the 'activation fee'.
Common red flags
- United support number found in a search engine advertisement rather than on united.com

- An agent asks for your MileagePlus password over the phone
- A recorded message offering a surprise status upgrade or bonus miles with a callback number
- After the call, the booking has not changed in the United app despite the agent's assurance
