United Airlines has launched a targeted promotion for those that wish to purchase Premier Qualifying Miles (PQM) and Premier Qualifying Segments (PQS) that count towards the elite status.
The price of PQM/PQS is variable (United here tries to maximize the cash that they get) and generally is not a good deal unless one needs these desperately.
You can try accessing this offer on United’s website here.
Remember that you can always buy elite qualifying and award miles using the Premier and Award Accelerators that you can apply to any itinerary purchased from United (even awards).
You have to also keep in mind that unless you have a waiver for PQD (Premier Qualifying Dollars) merely buying elite segments or miles is not enough.
PQM/PQS under this offer are expensive. I would only buy them if badly needed, the price is cheaper than using the Accelerators or unable to take a short break to get the miles/segments/dollars in the old fashioned way by flying.
