To start your search, head over to Delta’s website and log into your account. Once you’re in, hover your mouse over the SkyMiles menu on the top and you’ll see this menu appear:
By clicking on Certificates and eCredits you’ll be brought to a page that contains all of your unused tickets, eCredits and any companion certificates loaded into your account.
Choosing the certificate loaded into your account will show more details about the certificate, such as its number and the classes of service where it’s eligible. In the next steps you’ll be able to check availability for specific flights.

The next screen looks very much like the normal flight search that you might be used to. The search will be preset to two passengers. Depending on your certificate, you’ll be able to choose Main Cabin, Comfort+ or First Class.

Once you click “Search,” you’ll be able to see if a flight is available in the class of seat you select.

Once you select the flights and add them into your cart, the price you’ll have to pay, including the discount offered by the companion pass, will display.

If you’re curious to see more details about the actual pricing, click on the blue hyperlink on the right hand side titled “Taxes, Fees & Charges” to see a cost breakdown for each ticket including takes.
If you’ve reached this far, you’re good to go. Simply pay with either eCredits or your American Express Delta SkyMiles® card and your tickets will be issued.
It’s important to note that if you cancel a flight you booked with a companion certificate, you’ll get a credit for the primary ticket but you won’t get the companion certificate back. You’ll likely have the option to make a fee-free change to your flight to avoid losing your certificate, but changes are subject to seat availability and you’ll be charged for any fare difference of the primary ticket.
