My wife and I are flying to Phoenix to bring her father back to live closer to us. His health is failing him and we are going to be his guardians. We already have Power of Attorney and pay the bills. My wife selected Allegiant to fly on. No idea what she selected as whatever she wants is fine with me since it is her father. I love all the fees that Allegiant slaps on the bill. Fed Excise Tax - 19.68 gotta pay the tax man Segment Fees - 7.60 not sure what this is, but I guess it can't be included in the price they advertise. The flight to Phoenix? PFC - 9.00 This is what the Airports charge Allegiant, obviously, there is some profit built into this for Allegiant. Sept 11 Security Fee - 5.00 someone has to pay the TSA agents. It is us. Seat Selection Fee - 29.99 we must sit together on the way pack. Priority Boarding - 10.00 We did this as we want to be the first ones on the plane to get her Dad settled. Carrier Usage Charge - 20.00 not sure what this is. This seems to be some random dollar amount that Allegiant charges just because. Trip Flex - 10.00 this is in case he has another problem happen and we have to change out flights Carry On Bag - 26.00 Just a mere $150 in fees and taxes. I will be glad once this event is over and we proceed on to the next part of taking care of him locally and not trying to do it by phone and trusting people on the other end. I have learned that the Elderly Care Specialists in Phoenix do NOT impress me. I would have thought they were more knowledgable and compassionate down there where they deal with the elderly all the time, but they seem to be more nonchalant about it. We were paying for top notch care supposedly.
