Each upgrade is good for ONE-WAY travel.
The UA Systemwide Upgrade allows you to upgrade one-way from United Economy to United First in a 2-class aircraft, United Economy to United Business in a 3-class aircraft, or United Business to United First in a 3-class aircraft in Region 1 or Region 2.
This electronic upgrade is only valid on certain paid fares. Tickets using mileage (as well as tickets from some travel sites such as Priceline, Hotwire, etc.) are not valid for this upgrade. Please note that it is YOUR responsibility to contact United Airlines to confirm that your itinerary is eligible for upgrade using a Systemwide Upgrade electronic certificate.
Once you have confirmed eligibility for your itinerary, please email me the details of your itinerary including: record locator number (PNR), the passenger's first and last name name, flight number(s), destination and date of departure. I will contact United to sponsor your upgrades .
It's YOUR RESPONSIBILITY to verify that the upgrade is available for your itinerary and ticket class. I will not be responsible for itineraries that cannot be upgraded due to ineligibility, unavailability or any other reason
The upgrade would be yours to use on a future flight (before the expiry date) if the upgrades do not clear on these flights.
These are electronic upgrade certificates. I will upgrade your flights online. If there is upgrade inventory available, then your upgrades can be confirmed right away. If upgrade inventory is 0, you will be placed on a “waitlist” for the upgrade, which does NOT guarantee you will be upgraded on the flight as United confirm waitlisted passengers based on the status in its Mileage Plus program. So it is to your best interest to book flights with available upgrade inventory at the time of booking. When you call United Reservations, tell the agent that a friend is giving you “Electronic Upgrades” for your flights and ask for flights with available upgrade inventory. Please note that the upgrade inventory fluctuates constantly.
Most waitlists clear at the gate on the day of your flight. The earlier you are added to the waitlist the better your chances of upgrading.
As I have explained above, I can in NO WAY guarantee that space in first/business class will be available on your flights.
