I am a retired airline employee and love to travel but things these days change as did my plans.
I had to put off my trip by one day in Nashville and priceline refused to change my rental car reservation. The price was the same with there site for both days and there was plenty of cars available. Absolutely no flexability so I booked with Expedia and it was actually cheaper and they have a change/cancellation policy. I can see why the overall rating with priceline is so low.
