Most passengers are allowed one personal item (such as a purse or small backpack) plus one carry-on bag (that fits in the overhead bin) at no extra charge.
Basic Economy (or “Delta Main Basic”) fares may have restrictions (for example, carry-on bag may be limited) depending on route.
Here are the general fee guidelines. These apply to “standard travel company” checked bags (under the weight/size limits) for many domestic U.S. flights; international routes, premium cabins, status benefits will alter them.
For many Economy fares (Delta Main/Comfort) traveling within the U.S., the first checked bag is US$35 each way.
The second checked bag is US$45 each way.
Fees may differ for international routes, premium cabins or fares that include a free bag. For example, on some Europe/Asia routes the first bag may be free depending on the ticket.
Bags exceeding weight/size limits or exceeding typical “number of pieces” allowed will incur additional fees.
Examples:
On many domestic U.S. routes: Overweight 51-70 lbs (~23-32 kg) costs about US$100 each.
Overweight 71-100 lbs: about US$200 each.
Oversized beyond linear dimension (62 inches/158 cm +) may cost ~ US$200 or more.
Passengers in premium cabins (e.g., Delta One®, First Class, Business) often receive one or more free checked bags depending on route.
Elite members in Delta’s loyalty program (SkyMiles Medallion members) and certain credit-card holders may also receive free checked bag allowances.
Always verify your specific itinerary: some international flight or partner-carrier flights may follow different rules.
Here’s how and when you can add checked bags to your booking travel agency and what to expect.
According to Delta, you may select the number of checked bags and pay for them (or redeem miles for them) during check-in via delta.com, the Fly Delta® app or at a self-service kiosk.
Check-in for most flights opens 24 hours before departure; this is when you’ll typically see the option to “Add Bags”.
Some users report:
“You can add a bag any time after purchase by pulling up your reservation in the app or on the United site.” (Note: this was United but similar for Delta)
Unlike some airlines where prepaid bags (at time of booking) save you money, Delta’s policy appears to show the same bag fee whether you pay during check-in or at the airport kiosk. From Reddit:
“Unlike some airlines, Delta does not charge higher rates for baggage checked at the airport or checked online just prior to the flight.”
Some postings suggest the “pre-purchase” of bags (well before check-in) may not be available or may not give discount:
“Delta doesn’t do prebooked bags like many airlines in Europe. You can add a bag during check-in (online, starting 24 hours before your flight) or when you get to the airport. There’s no price difference.”
That means: you can add the bag later (during check-in or at airport), but you may not get a lower fee by doing so earlier. You may still pay the same standard fee.
Make sure you add the bag before travel or at check-in; leaving it until the gate or boarding may complicate matters (especially for Basic Economy or partner-operated segments).
If your flight has restrictions (embargoes, regional aircraft) you may be limited in how many bags you can add.
If you are uncertain how many bags you'll check, you might wait until check-in opens to add, but arrive early if you must do it at the airport.
| Checked Bag # | Fee (Typical U.S. Domestic) | Notes |
|---|---|---|
| 1st checked bag | US$35 each way | Under standard weight/size, subject to route/fare class |
| 2nd checked bag | US$45 each way | Same conditions apply |
| Overweight (51-70 lbs) | ~ US$100 | In addition to the bag number fee |
| Overweight (71-100 lbs) | ~ US$200 | Heavier bags cost more |
| Oversized beyond limit | ~ US$200 | Fee plus bag number fee may apply |
Always check the fare class and route: these determine if any free checked bags apply.
If you have elite status or a credit-card benefit, check if you get free checked bags.
Use the “Add Bags” option when check-in opens (~24 h before flight) to avoid last-minute issues.
Confirm weight & size limits to avoid overweight/oversize fees stacking on top of the standard bag fee.
For international flights, allowances can differ significantly — what applies domestically may not apply abroad.
For travel agency involving partner airlines or code-share segments, baggage rules may differ.
