Updated at 10pm PT on 5/10: It looks like some readers are getting up to 100% bonus offers from United Airlines.
Good afternoon everyone. United Airlines has a great buy miles promo currently running through May 24. It is a mystery offer, so depending on your account, you may see an offer for up to 75% bonus, or you might see a higher or lower offer. I checked my family’s United Airlines account and 75% bonus was the highest offer I saw, but it is possible that there are higher bonuses too. If you are a few hundred / thousand United Airlines miles away from redeeming for an award ticket, it might be a great idea to buy the remaining United Airlines miles. This promo runs for 2 more weeks and ends on May 24, so you have 2 weeks to decide. If you want to see other buy miles and hotel points promos, click here.
