Terrible! I had a family member pass away and missed my flight and they said well, because you didn't notify us 24 hours in advance you forfeited your flight; regardless of the travel insurance I purchased and the travel insurance documentation even says if there's a death you have 168 hourst to rebook. They told me their allegiant policy over rules the trip insurance document.... um then why did you sell it to me if it doesn't mean anything and the original rules of the ticket travel still apply? Well that's our "Prerogative." Click. SERIOUSLY? Worst customer service out of any company I've done business with, by far. Why would anyone fly with this company? First and last experience. Also, this was one of several calls I had put into them with either promises of automated call backs, within 1-2 hours, or after sitting on hold for a hour+ and then disconnected once someone "picked up" but chose to be silent and disconnect the call, or customer service saying they couldn't pull it up at that moment and would call me back... So despite my extensive attempt, a death in the family which was very difficult on its own, my purchasing travel insurance through them in case of emergency, I've completely forfeited my flight... voluntarily. In short, they have the WORST CUSTOMER SERVICE!
