What it is

One companion certificate each year after the card renews, starting in the second year of membership. It covers a Delta Main companion ticket on an eligible round trip from the U.S., Puerto Rico, or the U.S. Virgin Islands to the destinations in the certificate terms, including Mexico, the Caribbean, and Central America. You pay government taxes and fees, published as between $22 and $250 for itineraries of up to four segments. Delta Basic fares are not eligible.

How not to lose it

  • This resets with the calendar year. December is when most people remember, so book early if availability is limited.
  • Don’t wait for the last day. Statement credits can take days to post, and a purchase that settles after the window closes may not count.
  • Pay with the Delta SkyMiles Platinum. The credit only follows purchases charged to the card that carries it.
