Lufthansa seems to agree with us, as it’s currently running promotions with four different hotel chains this summer, all offering tons of different options for double-dipping on your rewards.IHG RewardsOne of my favorite brands for its purchasable elite status, IHG is offering up to a 50% bonus on Miles & More earnings this year:Promotion runs now through December 31, 2019 (for both stays and booking)Earning preferences on your account must be set to “Miles and More"Valid only at stays within the USNo registration requiredIt’s worth noting that — despite being marketed as a “50%” bonus — stays at the two limited-service brands that usually only award 1 mile per dollar spent (Staybridge and Candlewood) are actually offering a 100% bonus, as you’ll earn 2 miles/$ at these properties during the promotional period.You can earn bonus miles at European properties like the London Marriott Hotel Park Lane. (Image courtesy of the hotel)MarriottThough many have been less-than-positive about the Marriott Bonvoy program, the program itself remains robust, with the world’s largest hotel footprint and a new home-sharing platform seeking to compete with Airbnb.

They’ve jumped in on the Miles & More game as well, with the opportunity to earn up to 3,000 bonus miles on stays:Valid now through June 30, 2019Each stay earns a different bonus:Stay 1 you‘ll receive 500 bonus milesStay 2 you‘ll receive 1,000 milesStay 3 you‘ll receive 1,500 milesRegister here for the promotionNo specific date is noted for when the stay must be completed by, though the promotion states “April to July"If you max out this promotion, you’d take home 3,000 miles, worth $42 based on TPG’s valuations. Since Best Western properties tend to be quite inexpensive, this could be a great option to snag more valuable earnings than you’d otherwise get through Best Western’s own promotion.How to pay: Use a card like the Chase Sapphire Reserve (3x Ultimate Rewards points on all travel purchases) or Citi Premier® Card (3x points on hotels).Important ReminderJust note that for all of these promotions, you must elect to earn Miles & More miles instead of points in the given hotel program. That may make these less attractive for those of you looking to maximize your hotel stays, but for one or two nights at a property with limited use for you in the future, earning bonus miles could represent a solid option.
