United MileagePlus was once a great frequent flyer program offered by United Airlines. This airline is also part of the Star Alliance, the world’s largest Airline Alliance, with numerous airline partners. This program has multiple use cases. If you are not interested in purchasing these miles, you can always transfer Axis & HDFC bank points to United. Marriott is the option for Amex cardholders. As with the preferred partnerships, you receive 10,000 bonus miles on a transfer of 60,000 Marriott points, effectively creating a 2:1 transfer ratio.
Here are all the details about buying United Miles with a Bonus.

Bottomline
Buying United Miles can be helpful if you’re short of the required miles. However, opportunities to earn these miles exist in India. So, a top-up of miles could make sense for some. United’s main advantage is the low fuel surcharge. However, I would surely check the Avianca Lifemiles or Aeroplan points offer, as they have a fixed award chart and better miles requirements on some routes.
