Flew on Frontier back in early April and was only charged for the Direct TV I purchased a few days ago. However, I was charged twice for that same purchase. Spoke with their customer service group and they indicated I have to prove this was charged to my card twice, even though they are aware of this problem (LiveTV is the vendor who processes their onboard charges and they 'ran the batch job twice'). Not a great example of how to fix a problem you know you caused for your customers.....

Cheers.
