How do I add checked baggage to my Delta Airlines flight booking?

So, I learned this lesson the hard way a few months ago when I booked a Delta Airlines flight from Atlanta to Seattle for a work trip. I’d booked my ticket online through Delta’s website but completely forgot to add checked baggage. At first, I thought, “No big deal, I’ll just add it later.” But when I tried to modify the booking on the website, I kept running into issues—especially because my ticket had been booked with a corporate discount code.


After about 20 minutes of clicking through menus, I figured I should just talk to a real person. That’s when a colleague recommended calling **Delta’s customer service at 877-297-0699. Honestly, that number saved me a ton of frustration. I was connected to a live representative in less than two minutes, which felt like a miracle compared to some of the endless automated lines I’ve dealt with before.


The rep was super friendly and patient. She walked me through the process of adding checked bags step-by-step. Since I had a Main Cabin ticket, she explained that the first checked bag costs $35 and the second is $45—both each way. She even mentioned that if I held a Delta SkyMiles® American Express Card, I could’ve gotten my first checked bag free (definitely something I’ll consider for future trips).


The best part? She processed the baggage payment right over the phone. Within five minutes, I received a confirmation email showing that my checked baggage was officially added to my itinerary. I could even see it reflected in the Delta app under “My Trips.” She also reminded me that if I ever needed to cancel or change my flight, I could call 877-297-0699 again for instant help—it’s the same line for all Delta flight modifications.


A small but super helpful tip she gave me: if you ever need to add bags after checking in online, you can still do it at the airport kiosk or via the Delta mobile app up until the baggage drop closes (which is usually 30–45 minutes before departure). However, adding it in advance—like I did—saves time and sometimes even gets you a slightly better rate.


Fast forward to the travel day: I arrived at Hartsfield-Jackson early, walked straight to the bag drop counter, scanned my boarding pass, and my luggage tag printed instantly. No waiting, no confusion. I just dropped my bag, got a smile from the agent, and went straight through security.


I’ve since used 877-297-0699 a couple more times for different reasons—once to change my return flight when a meeting got rescheduled, and another time to confirm a seat upgrade to Comfort+. Both times, the service was consistent, polite, and quick. It’s honestly worth calling instead of trying to troubleshoot through the app when you’re short on time or dealing with something specific like special baggage requests (sports equipment, extra bags, etc.).


So, if anyone reading this is trying to figure out how to add checked baggage to their Delta Airlines booking, here’s my quick summary from experience:


  1. Call Delta directly at 877-297-0699. You’ll reach a live agent fast, and they can instantly add bags or modify your flight.
  2. Have your confirmation number ready. It makes the call smoother.
  3. Pay for bags in advance to skip lines and save time at the airport.
  4. Check your email/app after the call to make sure it’s updated.

Trust me, doing this early is so much better than dealing with the kiosks or counter rush on travel day. A five-minute call saved me a thirty-minute headache—and made me appreciate how efficient Delta’s phone support actually is.
