In the last couple of days, many Barclays cardmembers received a promotional email titled "Double Bonus Opportunity – Earn up to 60,000 miles!" or "...60,000 points!" or "...$600 Uber Cash!" This appears to be a widely targeted offer to all Barclays cards such as Arrivals cards, AAdvantage Aviator cards, JetBlue cards, Hawaiian Airlines cards, Wyndham cards, Uber card: between 11/10/2020 and 1/31/2021, you will earn up to 60,000 miles/points or $600 cash, depending on which card you have (e.g. 10x additional points on everything, up to 10,000 points earned, and additional 50,000 points when you spend a total of $3,000 within this period). This must be the best bonus ever for existing cardmembers since I started writing about credit cards in 2011; usually you need to open a new account and meet the minimum spending requirement to receive a bonus like this; mostly likely the existing cardmembers did receive a similar bonus when they opened the card, and now it is like receiving a second bonus to keep the card.
