Delta recently launched their 5 Summer Days of Deals events and while the first four days weren’t anything spectacular, their fifth day offer is actually worth looking into! With many Delta partner transactions, you’ll earn a 50% bonus on all miles earned, up to 10,000 bonus miles! Partners include anything from hotels, AirBnB, car rentals, Lyft, shopping online, dinning out, etc. All you have to do is register for the promotion by July 24th. All miles earned between July 21 and September 30, 2018 will count. While 10,000 bonus points sounds quite nice, the chances of earning that number of bonus miles are quite slim. For the average person, you’ll probably earn a few hundred to a few thousand points tops. Definitely still worth something to increase your point balance. For me personally, I’ll take advantage of this promotion mostly for Lyft rides. On Lyft rides you typically earn 1 mile per dollar spent, so with this offer you’ll earn 1.5 miles per dollar spent. For business travelers, however, you might do well on your car rentals. I know Adam rents with National a lot while on the road so being able to earn a 50% bonus for a car you’d be renting anyways isn’t too bad! Just remember though, the bonus miles earned are on any based miles, not any additional miles you might earn with another promotion.
