2019 Perktoberfest (free pretzels for DL AmEx cardholders)
 

This reminds me of previous summer cupcake/donut truck offers (2016 and 2017 IIRC), but this time DL is offering free pretzels In the fall.

DL AmEx credit card people are invited for this weekend, September 28-29 from noon to 4 pm in the Mall of America north parking lot: Show your card to claim an Angel Food pretzel for you and one for a guest.

This is from an email I received this morning, at about 8:30 am local time. It suggests that DL will be doing the same in other locations, just like previous offers. They've apparently already covered SLC, NYC, and DTW, with ATL, RDU, BOS, SEA, and LAX to come. There's some variation on times and some cities use different locations on Saturday and Sunday, so check the schedule carefully.

got that email! I might try to head there Sunday...
