United Airlines - Earn Upgrade Certificates

Did you know that after you have flown 10,000 miles with United Airlines (not on the partner airlines) but specifically United, the United Mileage Plus program will credit your mileage plus account with four/500 mile upgrade certificates. These upgrade certificates do have an expiration on them, so if you travel frequently on United, you might have upgrade certificates attached to your account number. So be sure to check your account number and take advantage of these promotional deals. Just let your travel agent know that you will be redeeming 500 mile upgrade certificates and they will be able to put you on the "upgrade list". Just make sure you know how many mileage credits you have and that you have enough. If you don't have enough, United will want you to purchase the additional you may need at the airport.
