Credit card companies usually publish a long list of additional perks for their cardholders. However, some credit card companies will take it a step further and offer more perks to get cardholders engaged even more and following them on social media. American Express and Delta are teaming up to do just that by giving away free pretzels, and all you have to do to qualify for a free pretzel is present a valid Delta-branded American Express card.

Amex and Delta started giving away pretzels on Friday, September 6 and will continue doing so until Saturday, November 2. The promotion is part of their 'Perktoberfest Tour'. The #DeltaAmexPerks pretzel truck is going to travel to nine cities in the United States and offer free, locally made pretzels to Amex cardholders who want a delicious treat.

To get a free pretzel, cardholders must show their American Express-branded credit card. They will receive one free pretzel for themselves and one for their companion. Those who don't possess an American Express card can buy a pretzel for $3, with proceeds going to the American Red Cross.

The #DeltaAmexPerks pretzel truck will visit the following cities, which happen to be where Delta has hubs or in focus cities for the airline:

  • Salt Lake City
  • New York City
  • Detroit
  • Minneapolis
  • Atlanta
  • Raleigh/Durham
  • Boston
  • Seattle
  • Los Angeles
