Delta's Online Check-in is an easy beginning to your travel experience, and you can do it from your home or office within 24 hours of your flight departure.
STEP 1. Visit Itineraries & Check-in at delta.com.
STEP 2. Submit your SkyMiles, confirmation, credit card, or eTicket number to access your itinerary.
At this time you can select passengers and number of bags and make any necessary changes (eg: view/change seat assignments and upgrade status, or pay for excess baggage, if applicable).
STEP 3. Print your boarding passes if you prefer to have them on paper. Or, at certain airports, you can go paperless and have an eBoarding Pass delivered right to your mobile device. Learn more about mobile check-in and see where it's available.
If you're not ready to print, you will be able to come back and print (or re-print) your boarding pass(es) at any time.
STEP 4. Drop off checked baggage at the nearest baggage drop at your local airport, marked with red "Baggage Drop" signage, or curbside check-in station.
Note: For travel outside of the United States, you will have your passport credentials checked by a Delta agent prior to boarding.
