Frontier passenger claims airline stole their seat — then stiffed them on a $250 refund

A Frontier Airlines passenger says a booking or seating problem left them unable to board a flight despite checking in and having a seat assigned. They allege the airline then marked them as a no-show and failed to provide a promised refund and $250 voucher, raising questions about how disrupted passengers are treated.

The passenger said their boarding pass showed seat “0” instead of 12D and that around 20 customers were left behind. After waiting about 30 minutes, they recall a gate manager offering a rebooking or a full refund plus voucher; two weeks later, neither had arrived. Other Reddit users described similar seat issues and suggested keeping records and contacting the US Department of Transportation. Frontier reported average airfare revenue of $67.82 per passenger in the third quarter, up 71% year on year, while total average revenue per passenger rose from $106.44 to $138.22.
