You got the increased bonus Delta Platinum card from July, the time is running out to get the $100 credit for a Delta purchase. You decide to book your hotel via http://www.delta.com. You then get an alert on your app and it turns out that your hotel booking with Delta does not code as a Delta purchase, but rather as Expedia or hotels.com. Does this make any sense? The most important thing is that whatever you buy must code as Delta. If you were flying and bought any drink or anything to eat, it would automatically code as Delta and you would get your $100 statement credit. It’s important to keep in mind that you don’t need to spend $100 to get $100. Any Delta purchase will get you the bonus. The crazy thing is that booking a hotel on delta.com won’t!
